Flag Football Uniforms: A Guide for Leagues, Schools and Dealers

The clearest numbers come from high schools. The participation survey of the National Federation of State High School Associations (NFHS) counted 102,360 girls playing flag football in the 2025-26 school year, up 48.7 percent from 68,847 a year earlier and up from 15,716 in 2021-22. Schools reporting the sport rose from 2,736 to 3,990, flag football entered the ten most popular girls' sports, and the NFHS expects 37 states to be sanctioning it or running independent or pilot programs by the following year.

Among younger children, flag is already the more common way to play. The Aspen Institute's State of Play 2025, drawing on data from the Sports & Fitness Industry Association (SFIA), reports that flag passed tackle among children ages 6 to 12 in 2017, and that 4 percent of that age group played flag in 2024 against 2.7 percent for tackle. From 2019 to 2024, flag participation at those ages rose 14 percent while tackle fell 7 percent. Teenagers still favor tackle, 6.4 percent to 2.8 percent at ages 13 to 17. The same report puts NFL FLAG, the National Football League's youth program, at more than 620,000 players ages 4 to 17 in 50 states.

Colleges are following. The National Association of Intercollegiate Athletics (NAIA), which launched women's flag football in 2021 in partnership with the NFL, approved it in June 2026 as its 30th championship sport. The first national championship is scheduled for spring 2027, and 60 NAIA institutions are expected to sponsor teams in 2026-27. In January 2026 the National Collegiate Athletic Association (NCAA) added flag football to its Emerging Sports for Women program in all three divisions. Its announcement cited sponsorship data from summer 2025 showing at least 40 schools planning varsity teams in 2025-26, which is also the number of varsity sponsors a sport needs before it can be considered for an NCAA championship. The same announcement notes the sport's addition to the 2028 Summer Olympics in Los Angeles.

For a uniform buyer, that growth has a practical side. A new program has no closet of last season's jerseys, no settled number list and often nobody who has placed a team order before. The rest of this guide is written with that buyer in mind, and our flag football and 7v7 page gives a short summary of the uniform.

Flag football is played without helmets or shoulder pads, and a play ends when a defender pulls a flag from the ball carrier's belt. That changes what the uniform is for. A tackle jersey is cut to cover pads and to survive being grabbed. A flag jersey is a light shirt whose job, beyond identifying the player, is to stay out of the way of the flags. The national youth rulebooks treat a deliberately covered flag as flag guarding, which is a penalty, so length, fit and the shorts matter more than in most sports. Our buying guide to custom football uniforms covers the padded game.

The jersey and shorts are the custom order. Our pages on game jerseys and team shorts describe those garments in general terms.

The flag belt is equipment, and who provides it depends on the organizer. NFL FLAG requires its own official belts and flags and issues them at check-in for its tournaments. USA Football's rulebook has the organization provide each player with a belt and a team jersey. The tournament rules posted by iFlag, an organizer of adult and youth events, make teams bring their own. Find out early, because the color of the flags limits the color of the shorts.

Extras need the same check. The college rulebook lists undershirts, headgear, sweatbands, armbands, socks and eyewear as parts of the uniform, and it does not let any undergarment hang below the waistline. Order team headbands, caps or sleeves only after the league has confirmed that players may wear them.

Flag football has no single rulebook. We read four that are published in full and one that is only partly public.

• NFL FLAG official playing rules. The edition linked from the league's rules page as its 2026 rulebook, for five-a-side youth play.
• USA Flag 5's Rulebook, version 2026.2. USA Football's five-a-side rules, with youth, junior and adult age groups.
• College Flag Football Rules, 2025-26 and 2026-27. The seven-a-side book used for NAIA women's flag football, written by a committee chaired by the NAIA with the National Junior College Athletic Association (NJCAA).
• iFlag Football Rules. General rules for adult men's, women's and coed tournaments and several youth formats. The edition posted describes itself as in effect for the 2023/2024 tournament season.
• NFHS Flag Football Rules Book. The high school book. The NFHS sells it in print and digital editions and does not post it free, but its points of emphasis for 2026-27 are public.

Pockets, belt loops and drawstrings

This is the rule buyers hear about first, and the documents differ on how strict it is. NFL FLAG only recommends shorts or pants without pockets or belt loops. USA Football bans both, adds that shorts should have no snaps, clips or zippers, and does not let players tape their way into compliance. The college book extends the pocket ban to the jersey. iFlag lets an official accept pockets that have been professionally sewn shut. Shorts with no pockets, no loops and the drawcord on the inside satisfy all four, and the NFL FLAG rules page gives the reason: they avoid penalties and finger injuries.

Jersey length and tucking

NFL FLAG and USA Football want every jersey tucked in before play begins. The college book goes further, listing a jersey that does not stay tucked as illegal equipment. iFlag is the outlier, accepting either a jersey long enough to stay tucked for the whole play or one short enough to end well clear of the belt. The NFHS states the principle in its 2026-27 points of emphasis: no clothing or hair may cover the flags or the belt.

Flags and the color of the shorts

Every source separates the flags from the shorts by color. The NFHS point of emphasis, which cites Rule 1-5-1f, calls for flags in one solid color that clearly contrasts with the shorts or pants, on a belt with three flags: one on each hip and one at the tailbone. It adds that manufacturer and school logos should not appear on the flags or belt. USA Football's wording is the widest, since the flags must contrast with all the colors on the pants. For design, the lesson is to keep the shorts simple. Side panels and stripes add colors, and each added color is one more that could match a flag.

Numbers, jewelry and headwear

Only the college book sets a number standard among the documents we read: numbers on the front and back, from 0 through 99, with no zero in front as in 04 or 00, in permanent Arabic numerals, and with no two teammates on the field in the same number. On headwear the books run from NFL FLAG, which allows headbands and winter beanies along with secured soft-shell helmets, to the college book, which permits cloth headbands and hats only if the logos on them are the manufacturer's or the school's.

Buyers use 7v7 for two different games, and the uniform questions are not the same. The first is seven-a-side flag football. The college rulebook sets teams of no more than seven players, and high school girls' flag football under NFHS rules is a seven-player game as well. NFL FLAG's rules page notes that college teams and some other leagues play 7 on 7, allow certain kinds of contact, and in some cases require soft-shell helmets. These teams wear the flag uniform described above, under the rulebook of their own association.

The second is 7v7 passing: leagues and tournaments built around quarterbacks, receivers and defensive backs, aimed largely at high school players. iFlag publishes rules for it beside its flag rules. In that version an official counts four seconds from the snap for the quarterback to throw, there is no kicking, and protective headgear is strongly encouraged but not required.

We found no single national rulebook for 7v7 passing. Each organizer publishes its own rule sheet, and many are not posted publicly, so the tournament director is the person to ask. These are the questions that affect a uniform order.

• Must jerseys match, and must they carry numbers on the front, the back or both?
• Does each team need a light and a dark jersey?
• Is headgear required, and is a particular type specified?
• Are flags worn, and if so, who supplies them and in what color?
• Are there limits on team names, logos or sponsor marks?

A team that travels to tournaments does not know its opponents' colors until the bracket is posted. That makes it the clearest case for a second jersey in a contrasting color.

A flag jersey is knitted, not woven. The Textile Resource Library at Pratt Institute describes a knit as yarn formed into a continuous series of connected loops, and that looped structure is what lets the fabric stretch and move with the body. In a game played at a sprint, with players reaching for flags and for the ball, stretch and low weight count for more than the toughness a padded jersey needs.

Three knits worth knowing

• Jersey knit. Made on one set of needles. It stretches across its width, and it can run if it is snagged.
• Interlock. A double knit made on two sets of needles, which looks the same on both faces. It is thicker and less stretchy than jersey.
• Tricot. A warp knit, in which the loops run lengthwise, made from filament yarn that is usually a synthetic such as nylon or polyester. It is firm, stretches crosswise and resists snags, and Pratt lists activewear among its uses.

Team jerseys are mostly polyester, which is also the fiber that sublimation printing needs. Beyond that, the specifics depend on the manufacturer. Fabric names, weights, whether the body is a flat knit or an open mesh, and whether the side panels are cut from a stretchier fabric all vary. Ask for the composition of each panel, and ask for a sample you can handle.

Why jerseys are cut long or fitted

Length and fit come from the rules, not from fashion. Where a rulebook requires tucking, the jersey needs enough length to stay inside the waistband when a player raises both arms or twists away from a defender; the college book says so directly by requiring a full-length jersey. A body that is loose through the waist can blouse over the belt and cover the flags, which is the argument for a closer cut. Where a league accepts the alternative in iFlag's rules, a jersey that ends well above the belt can replace tucking. Settle which approach your league allows before a pattern is chosen, because length cannot be added afterward.

Shorts follow the same logic: an elastic waist with the drawcord inside, no pockets, no loops, and legs that do not flap over the flags.

Numbers, names and logos are either printed into the fabric or applied on top of it. In dye sublimation, heat turns the dye into a gas that enters the polyester fiber and is trapped there as the fiber cools, so the design becomes part of the fabric. Screen printing and heat-applied numbers put a layer of ink or film on the surface. Our guide to sublimation, screen printing and embroidery compares the methods in detail. For flag football, sublimation has four things in its favor.

• Nothing sits on the surface. The jersey stays as light and as stretchy as the fabric itself, and there is no layer to crack or peel when a defender's hand drags across it.
• Every player is printed with the design. Each number and name is part of the same print, so a roster of different numbers adds no separate step.
• Color is open. Stripes, fades, a full-color logo and the shorts can all be designed together.
• A second jersey is the same pattern. The dark and the light jersey can share one design with the colors exchanged.

Sublimation has limits. It needs polyester or a polymer-coated material, so it is not a method for cotton. And freedom of design is not freedom from the rules. A number still has to be clearly visible, so keep it in one solid color that contrasts with the jersey behind it, and keep patterns and fades out of the number area.

Stock jerseys with screen-printed or heat-applied numbers remain a reasonable choice for a recreational league that hands out pre-numbered shirts by size. Ask how the numbers hold up to washing, and pass the care instructions on to families.

Where your rulebook sets no number rule, adopt a sensible standard anyway, so the jerseys stay usable if the rule tightens or the team enters another competition: numbers on the front and back, readable from the sideline, in one solid color. The college standard of at least 8 inches on the front and 10 on the back is the most demanding we read. On small youth jerseys, check that numbers of that height actually fit.

Keep one number list for the whole team, or for the whole league if jerseys move between teams. One person checks that no two teammates share a number and sets aside a few unused numbers for spare jerseys.

Names are optional in the rulebooks we read. In a youth league, weigh two things before adding them: privacy, since some leagues print a first name or no name at all, and reuse, since a named jersey belongs to one child. Send each logo as the cleanest file you have; our guide on how to prepare a logo for uniform printing explains which file types work.

What a college jersey may carry

The college book gives a closed list of what a jersey may show besides the number: the player's name, the school and mascot names, sleeve stripes, logos for the school, conference, mascot, a postseason game, a memorial or the military, a captain's C, and the American flag or a state flag. A sponsor's logo is not on that list. High school programs should put the same question to their state association.

Sponsors

The two youth rulebooks we read say nothing about sponsor logos, which leaves the decision to each league. Where sponsors are allowed, get each sponsor's written approval and its own artwork file, and fix the position and size across all teams so every sponsor is treated alike.

NFL team names and logos

Playing under an NFL club's name is part of the NFL FLAG program. Its website states that the program is operated by RCX Sports under license from the National Football League, and that NFL team names, logos, indicia and uniform designs are trademarks of the teams. Leagues in the program outfit their players in club-branded uniforms supplied through it.

An independent league, a tournament team or a manufacturer outside that program does not gain those rights by playing the same sport. Putting an NFL club's logo, wordmark or uniform design on a custom jersey needs the owner's permission. The practical route is an original identity: team names, mascots and colors of your own. Expect a manufacturer to ask you to confirm that you have the right to use every mark in a design. This is general information, not legal advice.

Without pads, a flag jersey is sized to the player. Use the size chart for the exact garment, not a T-shirt size, and add one test that other sports do not need. With the jersey tucked in and a belt on, have the player reach overhead and twist. If the hem comes out, go longer.

Girls' and women's cuts

Much of the sport's growth is in girls' high school and women's college teams, and those players should not be handed a boys' size run by default. Men's or unisex, women's and youth garments are cut on different patterns, so the same letter size measures differently in each. Choose the cut with the players, let them try samples where a manufacturer can supply them, and record the cut with the size on the roster, as in Women's M. Ask about shorts separately: length is a matter of preference as well as fit, and a player's jersey and shorts are often different sizes. A coed adult team may need both cuts in one order.

Youth players

Children in their growth years change size quickly. Collect youth sizes as close to the order date as the schedule allows, from a current measurement and never from age or grade. A recreational league that hands out jerseys after registration may have no chance to measure anyone; it orders a spread of sizes and needs a plan for exchanges. Our team uniform sizing and roster guide explains how to measure players and build the roster.

A reversible jersey or two jerseys

Several rulebooks expect a team to be able to change color. USA Football puts home teams in dark jerseys and visitors in light ones, and an approved ruling in its book has the visitors change if both teams arrive in dark, unless the coaches and officials agree that the contrast is sufficient. The college book puts visitors in white, and iFlag has each team carry a dark and a light shirt. There are two ways to comply.

• A reversible jersey. One garment to pack and nothing to leave at home. Ask how it is built, as two layers sewn together or as one fabric printed on both faces, because that decides its weight and warmth and whether the inner design shows through. The number has to appear on both sides, and damage to one side takes both out of use.
• Two jerseys. Each is a single light layer that can be washed, repaired and replaced on its own. The team has twice as many garments to buy, track and bring to games.

Check the wording before you choose colors. Gray or yellow is a light color, but it is not white, and the college book names white for visitors.

A whole league

A league that buys for every team is building a system. One template in several color combinations keeps the teams distinct and the league consistent, and one roster format stops each coach inventing a new one. The hard part is timing, because sizes and names depend on registration. Leagues handle it in one of two ways. Some order pre-numbered jerseys in a spread of sizes and assign them at the first practice. Others wait for final rosters and print a name and number for each player. The first is quicker and leaves no jersey tied to one child; the second fits better and needs a firm registration deadline. Either way, plan spare jerseys for late sign-ups. USA Football's rulebook recommends rosters of no more than 15 players, a useful ceiling when estimating quantities.

One team

A school, tournament or adult team orders from a roster: the name as printed, a number, and a size for each garment, usually with a second jersey. One person should own the roster and the approval.

Planning backward from the first game

Custom uniforms are made after the order is placed, so start from the day the team must have them and work backward. This guide gives no durations on purpose. Plan only on times that a manufacturer confirms in writing for your order.

1. Fix the in-hand date. The first practice in uniform, picture day or the opening game, whichever comes first.
2. Subtract delivery. Ask how the order ships and how long transit and customs clearance take.
3. Subtract production. Ask for the current production time for your quantity and decoration, and what starts the clock.
4. Subtract proofing. Allow for corrections, and for someone to check every name, number and size.
5. Subtract registration, sizes and approvals. A league board, a school purchasing office or a sponsor may each need to sign off.

The date left over is the real deadline for starting. Our uniforms are made to order in Sialkot, Pakistan, so an order for a U.S. league includes international transit; contact our team about the timing for yours. Every order goes through an artwork proof that lists every player, and nothing is produced until you approve it. Our team prepares the proof from the colors, logo and roster you send us on WhatsApp. How it works describes each stage.

What drives the cost

This guide contains no prices, because a figure quoted without your quantities and design would mislead. These are the factors that move a quote.

• Pieces per player. A jersey alone, a jersey and shorts, or two jerseys and shorts.
• Decoration. Sublimation prints everything at once; applied numbers and names are separate steps.
• Construction. A reversible jersey, contrast panels or a special fabric take more to make than a plain single layer.
• Quantity. Setup work is spread over more garments in a larger order; how that affects a quote depends on the manufacturer.
• Schedule. A compressed schedule or faster freight costs more than a planned one.
• Mistakes. A remake caused by a wrong name, number or size is the most avoidable cost on the list.

Dealers who supply several leagues or schools should ask about pricing structure and reorders at the start. Our trade page is written for businesses that order regularly.

Each of these problems can be caught before production starts.

• Shorts designed before the flags are known. If the two match, one of them has to change.
• Pockets, belt loops or an outside drawstring. Legal in some leagues and a penalty in others.
• A jersey too short to stay tucked. It comes out on the first reach and covers the flags.
• Numbers that blend into the design. Tonal, patterned and outline-only numbers look sharp on a screen and are hard to read on a field.
• One jersey where the rules expect two. Or a light jersey where the rule says white.
• NFL club marks on an independent league's jerseys. The names, logos and uniform designs are the teams' trademarks.
• A boys' size run for a girls' team. The cut is different, not only the size.
• Headwear ordered before the league approved it. Caps and beanies are allowed in some rulebooks and removed in others.
• Counting back from the first game. The uniforms are needed earlier, and proofing comes before production.

With every row checked, the artwork proof brings the design, numbers, names and sizes together in one document. It is the last point at which a mistake can be corrected before it is made into a garment.
