Quick Answer
Men’s and youth lacrosse uniforms are a jersey cut to fit over shoulder pads and arm pads, plus shorts in one team color. For NFHS high school boys in 2026/27 the jersey must be a single solid color, white at home and non white away. Numbers must contrast and be at least 8 inches tall on the front and the back, legal numbers are 0 to 99 with no duplicates, and shorts are the same dominant color across the team. NCAA men’s rules ask for 10 inch front and 12 inch back numbers. USA Lacrosse youth rules only require a jersey and shorts in the same color as teammates. A custom sublimated jersey and shorts set with names, numbers and crest costs $79.99 per set at 1 to 24 pieces and $69.99 at 101 plus from Hamco, youth YS to adult 4XL at the same price. A free mockup comes back in 12 hours, production is 3 weeks and there is no minimum order.
Men’s lacrosse uniforms and youth lacrosse uniforms are the same garment in two sizes, and the mistakes buyers make are the same too: numbers too small for the rule book, a jersey that fits before the pads go on and not after, and a reorder that comes back in a different shade. This guide is written for the person who places the order, whether that is a 12U travel club manager, a high school athletic director or a men’s club treasurer. It covers the uniform rules by level, how youth and men’s fit differ, what fabric and cut to buy, and what the order costs at published prices. Every rule is quoted from the rule book with the rule number, and every price comes from a custom lacrosse uniforms product page, both read on October 6, 2026.
One scope line so this page does not repeat our others. The pads and helmets a player must own are covered in the coach’s game day gear checklist with the NFHS equipment rule next to each item, and the standards behind them are on the USA Lacrosse equipment page. Girls’ and women’s uniforms run under different rules and a different cut and have their own guide. This page is only about the uniform itself for boys and men: jerseys, shorts, numbers, fit, fabric and cost.
What are the NFHS lacrosse uniform rules for 2026/27?
High school lacrosse uniforms in most states run under the NFHS Boys Lacrosse Rules, and the uniform rule is Rule 1.9.1h, with shorts in 1.9.1i and logos in 1.9.1j. The NFHS publishes a one page boys lacrosse uniform sheet with the same rules in a diagram; it still shows the old 12 inch back number, which changed for 2026. The table is the rule text as it stands for the 2026/27 season.
| Uniform item | NFHS boys Rule 1.9.1 text (2023 book, with the 2026 change noted) | What to put on the order |
|---|---|---|
| Jersey color | Jerseys shall be of a single, solid color. The home team shall wear white jerseys and the visiting team shall wear non white jerseys; the visiting team is responsible for avoiding similar colors | One white set and one dark set, or a white set plus pinnies if the budget only covers one |
| Trim | Collar, cuffs and waistband may contrast up to 2 inches; side inserts may contrast up to 3 inches wide from armpit to waistband; piping up to 1/8 inch | Side panels no wider than 3 inches; tell the designer the limits before the mockup |
| Numbers | Centered front and back, contrasting with the body; at least 8 inches tall on the front and, from 2026, at least 8 inches on the back (it was 12); contrasting trim on the number up to 2 inches | 8 inch numbers front and back; older 12 inch back numbers are still legal |
| Legal numbers | Legal numbers are 0 to 99; 01, 02, 03 are not legal; duplicate numbers on one team are not permitted | Lock the roster before the mockup and do not use leading zeros |
| Pads | The jersey shall completely cover the shoulder pads | Order the cut that goes over pads, and size over pads |
| Shorts | All players on the same team shall wear uniform shorts of the same dominant color | One short color per team; practice shorts can differ |
| Under jerseys and compression shorts | If visible, the same color for all teammates who wear them; the 2026 editorial change allows white, gray, black or a team color | Pick one under color for the team and put it on the order sheet |
| Logos | A manufacturer’s logo may not exceed 2 1/4 square inches; one per item; an American flag up to 2 by 3 inches and, by state adoption, a memorial patch up to 4 square inches | Sponsor patches are fine; keep the maker’s mark small |
Two things from the NFHS 2026 rule changes matter for the order. The back number minimum dropped to 8 inches, matching the front. A jersey built to the old 12 inch rule is still legal, and a new jersey needs 8 inches on both sides. And mouthguard color limits were removed, which has nothing to do with the uniform but often comes up in the same meeting. The NFHS release of August 13, 2026 about the 2027 season adds a shot clock and new ball colors and lists no uniform change. What is on this page should hold through the 2026/27 season.
What are the lacrosse jersey number rules at each level?
Lacrosse jersey number rules change with the rule book, not with the age of the player, and buyers mix them up because the same jersey maker serves all three. Here is what each book says, with the rule reference.
| Rule book | Front number | Back number | Other number rules |
|---|---|---|---|
| NFHS boys (high school), Rule 1.9.1h | At least 8 inches | At least 8 inches from 2026 (was 12) | 0 to 99, no leading zeros, no duplicates, number contrasts with the body, trim up to 2 inches |
| NCAA men’s, Rule 1 Section 21b | At least 10 inches, centered | At least 12 inches, centered | 0 to 99 recommended; numbers must clearly contrast; duplicates not permitted (Section 23d); white or light jerseys at home unless both coaches agree |
| USA Lacrosse boys youth 2026, player equipment rule | No size stated | No size stated | A jersey and shorts of the same color(s) as teammates; the youth book also lists the NFHS 8 inch change under notable high school changes, so ask your league which book it follows |
The practical answer for lacrosse jersey numbers is to build every boys’ and men’s jersey with an 8 inch front and 8 inch back number. The exception is a program that plays NCAA rules, where the back goes to 12 inches and the front to 10. On a youth small jersey an 8 inch number fills most of the back, which is why youth programs sometimes ask for 6 inch numbers on youth lacrosse jerseys. That is fine under the youth book, but it will not pass an NFHS official if the team plays up into a high school league. The font matters as much as the height for the official reading it from 60 yards. Our best jersey fonts guide covers which number fonts stay readable on a sublimated jersey.
How do men’s lacrosse uniforms differ from youth lacrosse uniforms?
Three ways: the size chart, the cut over pads, and how much of the jersey the number takes up. Men’s lacrosse jerseys and youth lacrosse jerseys use the same pattern logic, scaled. The rule book does not change between a 14U travel team and a varsity squad in most leagues, so the differences are fit and proportion, not rules. The size chart below is Hamco’s published chart for lacrosse. Youth sizes run YS to YXL and men’s XS to 4XL, and the two overlap at the top of youth and the bottom of men’s. Hamco notes that sizes may vary by style and that custom sizing is available.
| Youth size | YS | YM | YL | YXL |
|---|---|---|---|---|
| Chest, inches | 26 to 28 | 29 to 31 | 32 to 34 | 35 to 37 |
| Waist, inches | 22 to 24 | 25 to 27 | 28 to 30 | 31 to 33 |
| Men’s size | XS | S | M | L | XL | 2XL | 3XL | 4XL |
|---|---|---|---|---|---|---|---|---|
| Chest, inches | 32 to 34 | 35 to 37 | 38 to 40 | 41 to 43 | 44 to 46 | 47 to 49 | 50 to 54 | 55 to 60 |
| Waist, inches | 26 to 28 | 29 to 31 | 32 to 34 | 35 to 37 | 38 to 40 | 41 to 43 | 44 to 48 | 49 to 54 |
Read the chart over pads, not over a T shirt. The jersey has to completely cover the shoulder pads under NFHS Rule 1.9.1h(5), so the chest measurement that matters is taken with the shoulder pads and arm pads on. A 13 year old with a 33 inch bare chest is a YL on paper and may need a YXL or an adult S once the pads are on. For a men’s club roster, the same rule applies and the spread is wider: a 5 foot 6 attackman and a 6 foot 4 long pole can be three sizes apart, and both count toward the same price tier. The lacrosse positions guide explains why the long pole defender is usually the biggest jersey on the order. Youth programs that outgrow sizes every season should order one or two extra YL and YXL youth lacrosse jerseys. A single replacement is priced at the 1 to 24 tier and comes back in the same colorway when reordered against the original order.
Which fabric and cut should you buy?
Every Hamco lacrosse jersey is about 150 GSM sublimated polyester pro mesh, per the product pages. That is the same weight for youth and men’s, and the fit difference is in the pattern, not the fabric. Sublimation prints the colorway and side panels into the fabric before sewing. Tackle twill is sewn on for the front and back numbers, the chest crest is embroidered and sponsor patches are screen printed, and all four are included in the price. The what is sublimation printing guide explains why the body never cracks or peels while twill is the part that can lift after years of washing. Here are the cuts of men’s lacrosse jerseys and youth jerseys and when each one makes sense for boys’ and men’s programs.
| Cut | Spec from the product page and who it suits | 1 to 24 | 101 plus |
|---|---|---|---|
| Standard uniform set, jersey and shorts | 150 GSM pro mesh jersey cut over shoulder pads and arm guards, matching shorts with elastic waist and drawcord, color locked from the same dye batch. The default for high school and men’s game day | $79.99 | $69.99 |
| Standard jersey alone | Same jersey sold individually, for a second colorway or single replacements | $44.99 | $36.99 |
| Sleeveless jersey | Sleeveless athletic cut over shoulder pads for hot weather; the shoulder pads must still be fully covered to pass NFHS Rule 1.9.1h(5), so confirm the pad style before choosing it | $39.99 | $32.99 |
| Full sleeve jersey | Wrist to wrist coverage with UPF sun protection, built for box lacrosse and cold early spring field play | $38.99 | $32.99 |
| Game shorts alone | 150 GSM polyester, elastic waistband, internal drawcord, pocketless game cut so nothing catches a stick | $39.99 | $32.99 |
| Reversible pinnie | 140 GSM single layer micro mesh, two sublimated sides, for practice and tryouts; not a legal game jersey under the solid color rule | $49.99 | $39.99 |
| Shooting shirt | 150 GSM performance polyester from the same artwork as the jersey, for warm up | $34.99 | $26.99 |
For a youth program the honest advice is the standard set and nothing else in year one. For high school lacrosse uniforms, the set plus a second jersey color covers the home white rule without buying two sets of shorts. The shorts rule only asks for one dominant color across the team. For a men’s club, the sleeveless jersey is the hot weather option, but check two things first: that the league plays NFHS or NCAA rules, which require the shoulder pads covered, and that the players’ pads are the low profile kind that a sleeveless cut can cover. The full sleeve jersey is the one the product page builds for box lacrosse and cold early season field play; our box lacrosse vs field lacrosse guide explains the gear difference.
What do men’s and youth lacrosse uniforms cost in 2026/27?
Hamco publishes one price per piece in four tiers, and youth and adult sizes count toward the same tier in one order. The set includes names, numbers, the crest, a free mockup within 12 hours and shipping, with no setup fee and no minimum. The chart shows what five real order sizes come to, from a 15 player 12U team to a 120 set youth league order.
Read the chart as a buyer, not as a chart. A 12U team of 15 pays $1,199.85, and a men’s club of 22 pays $1,759.78 at the same $79.99 per set. A high school ordering varsity and JV together, 40 sets, drops to $76.99 and pays $3,079.60, which is $120 less than two separate orders of 20 at $79.99. A varsity program that buys home and away sets at once, 60 sets, reaches $74.99 and pays $4,499.40. A youth league that pools six teams into one 120 set order pays $69.99 a set, $8,398.80 in total, and saves $1,200 against the top tier. The lesson is the same at every level: combine squads, combine home and away, and let the youth sizes and adult sizes ride in one order, because the tier is counted on pieces, not on sizes.
How do you order so the jerseys arrive legal and on time?
- Write the rule book on the order. Say NFHS, NCAA or USA Lacrosse youth, and ask for 8 inch numbers front and back (10 and 12 for NCAA). The product pages say numbering follows NFHS visibility standards, but the number height goes on your mockup notes, so write it.
- Lock the roster numbers first. No duplicates, no 01 style numbers, 0 to 99 only. A duplicate caught at the mockup costs nothing; one caught by an official costs a game.
- Measure over pads. Have every player stand in shoulder pads and arm pads and take the chest measurement then. Anyone between sizes goes up.
- Choose one shorts color and one under jersey color for the whole team and put both on the order sheet, because the rule applies to everyone who wears them.
- Approve the home and away mockups together so the crest, fonts and panel widths match. Our best jersey color combinations guide helps pick a white and a dark that still read as one program.
- Order 4 to 5 weeks before the first game. Standard production is 3 weeks from the approved mockup and standard shipping inside the continental United States is 3 to 5 business days. Rush production is 10 business days for $250 or 20 percent of the order, whichever is higher, per the shipping policy. Custom orders are not returnable per the refund policy, so the measuring step is the one you cannot skip.
For the roster sheet, payment collection and parent communication side of the order, our how to order team uniforms guide and the pre season ordering checklist cover it step by step. If the program is new and still picking a name, the lacrosse team names list is a good place to start.
Frequently Asked Questions
What size do lacrosse jersey numbers have to be?
NFHS high school boys: at least 8 inches tall on the front and the back for 2026, down from 12 inches on the back. NCAA men: at least 10 inches on the front and 12 on the back. USA Lacrosse youth rules do not set a size and only ask for a jersey and shorts in the same color as teammates, so most youth programs follow the NFHS 8 inch rule.
What color do high school lacrosse jerseys have to be?
Under NFHS Rule 1.9.1h the jersey is a single solid color. The home team wears white, the visiting team wears non white, and the visiting team is responsible for avoiding a color clash. Numbers must contrast with the body. NCAA uses white or light at home unless both coaches agree otherwise.
Are youth lacrosse uniforms different from men’s lacrosse uniforms?
Only in size and proportion. The cut over pads, the 150 GSM fabric and the number rules are the same in most leagues. Youth sizes run YS to YXL (chest 26 to 37 inches) and men’s XS to 4XL (chest 32 to 60 inches), and both cost the same per piece at Hamco.
How much do men’s lacrosse uniforms cost?
A custom sublimated jersey and shorts set with names, numbers and crest is $79.99 per set at 1 to 24 pieces, $76.99 at 25 to 50, $74.99 at 51 to 100 and $69.99 at 101 plus from Hamco. Shipping is included and there is no setup fee. A jersey alone is $44.99 to $36.99.
Do all players on a lacrosse team have to wear the same shorts?
Yes under NFHS Rule 1.9.1i and NCAA Rule 1 Section 21c: all players on a team wear shorts of the same dominant color. Visible compression shorts and under jerseys must also match across the players who wear them.
Final thoughts
Men’s lacrosse uniforms and youth lacrosse uniforms come down to four decisions: the rule book you play under, the number size that book asks for, a size chart read over pads, and an order combined across squads so the tier price drops. Get those four right and the jersey is legal the day it arrives and still matches when you reorder in year three. The most common failure is not fabric or color. It is a 6 inch number on a high school jersey or a duplicate 7 on a roster nobody checked.
