Grappling shorts are the final piece of the no-gi academy kit.

Once you have custom rash guards on your students, the natural next step is matching shorts. A team with coordinated rash guards and grappling shorts looks completely different at competitions and seminars from a team wearing a mix of whatever everyone ordered individually online. The visual impact is immediate.

Custom grappling shorts are also the easiest and most affordable item in the custom academy gear range to produce. They have shorter lead times than gis, lower MOQ requirements than most items, and — when ordered together with rash guards from the same supplier — can be colour-matched exactly to create a complete no-gi uniform.

This guide tells you everything you need to know before placing your order.

Why grappling shorts complete your no-gi kit

The no-gi academy kit has three components: rash guard, grappling shorts, and optionally spats. Most academies build the kit in this order: rash guards first (highest visibility, lowest MOQ), then shorts (completes the uniform), then spats (optional addition).

The reason matching shorts matter goes beyond aesthetics. When your students show up at a tournament in a complete, matching kit — same colours, same logo, same design language on both garments — it signals a professional, organised academy. It is the kind of visual identity that attracts new students and makes existing students proud to represent the gym.

For the gym’s revenue model, shorts also offer a practical advantage. They wear out faster than rash guards — the stress points at the waistband and inner thigh see significant friction during training. Students typically go through two to three pairs of shorts for every rash guard they wear out, which means recurring revenue from restocking if you are selling through the academy.

Grappling shorts vs MMA shorts — the key difference

This is one of the most common ordering mistakes gym owners make on their first custom kit. Grappling shorts and MMA shorts look similar but are designed for different purposes — and in IBJJF competition, only one of them is legal.

Feature	Grappling shorts (BJJ)	MMA shorts
Velcro	None anywhere — zero Velcro	Often has Velcro at waist closure
Inseam length	11–13 inches (longer)	6–10 inches (shorter)
Leg opening	Fitted or slightly flared	Heavily flared for kicking mobility
External pockets	None	Sometimes included
IBJJF no-gi legal	Yes — if inseam requirement met	No — Velcro disqualifies immediately
Best for	BJJ training + no-gi competition	MMA training + striking sports

Critical rule: If any student competes in IBJJF no-gi events, their shorts must have absolutely no Velcro. A Velcro waistband closure will result in disqualification before the match begins. Always confirm with your supplier that the shorts are “zero Velcro” — not just “Velcro-free waistband.” Velcro on pockets or decorative panels is also prohibited.

Fabric options for custom grappling shorts

Three fabric types dominate the custom grappling shorts market. Each has specific strengths depending on your academy’s priorities.

100% polyester (sublimation-ready)

The most popular choice for custom academy grappling shorts. 100% polyester accepts sublimation printing better than any other fabric — producing vivid, long-lasting colours that will not fade, crack, or peel with washing. Lightweight and moisture-wicking. Slightly less durable at stress points than ripstop nylon but holds up well for most training environments. Best for academies prioritising design quality and colour accuracy.

Ripstop nylon

A woven fabric with a distinctive crosshatch reinforcement pattern. Extremely tear-resistant — the ripstop weave prevents small tears from spreading. More durable at stress points than polyester. However, ripstop nylon does not accept sublimation printing — it typically requires screen printing or embroidery, which limits design complexity and colour options. Best for academies prioritising maximum durability over design flexibility.

Polyester-spandex blend

Adding 5 to 15% spandex to the polyester base creates a stretch fabric that moves more freely with the body. Some practitioners prefer this for guard-intensive training where leg mobility is critical. The blend still accepts sublimation printing though not quite as vividly as 100% polyester. A good middle ground for academies whose students prioritise mobility.

Fabric	Sublimation	Durability	Stretch	Best for
100% polyester	Excellent ✅	Good	Minimal	Design-first academies
Ripstop nylon	Not compatible ❌	Excellent	Minimal	Durability-first training
Poly-spandex blend	Good ✅	Good	Good	Mobility-focused training

Recommendation for most academies: 100% polyester with full sublimation. It gives you unlimited design options, vivid colour matching with your rash guards, and sufficient durability for regular training. The fabric weight should be 120 to 150 GSM — light enough for comfortable training without feeling paper-thin.

Sublimation vs screen printing for grappling shorts

The same principle applies here as with rash guards — and the answer is the same.

Sublimation printing infuses ink directly into the polyester fabric. The design becomes part of the material — it cannot peel, crack, or fade. For grappling shorts specifically, sublimation is ideal because the waistband area, leg openings, and inner thigh are all high-stress flex zones. A surface-applied print in these areas would degrade quickly.

Screen printing sits on top of the fabric surface. It will crack and peel at flex points — waistband, inner thighs, behind the knee. For polyester grappling shorts, screen printing is not appropriate for daily training gear. It may be acceptable for limited-edition event shorts that will not see regular training use.

Embroidery is used only for patches or small logo placements on the waistband or leg — never for all-over design on grappling shorts. Some academies add an embroidered patch to an otherwise sublimated short for a premium look.

Bottom line: Order sublimation-printed grappling shorts. For ripstop nylon shorts where sublimation is not possible, work with your supplier on embroidered patches as the branding method — accepting that design complexity will be limited.

IBJJF compliance rules for grappling shorts

If your students compete in IBJJF no-gi events, the grappling shorts must meet specific requirements. These rules exist to protect competitors from mat burn caused by exposed hook-and-loop Velcro on an opponent’s gear.

IBJJF rule	Requirement
Velcro	Zero Velcro anywhere on the shorts — not the waistband, not pockets, not decorative panels
Inseam length	Minimum 11 inches for adult competitors
Shorts must not extend past the knee	Maximum length — below the knee is not permitted
Colour	No specific colour requirement for shorts (unlike the gi)
Design	No offensive imagery. Academy logos and branding permitted.

Always download the current IBJJF rulebook and verify these requirements before your production run. Rules are updated periodically — the table above reflects rules as of May 2026 but should be confirmed against the live rulebook for any competition use.

Waistband types

The waistband is the most structurally important part of grappling shorts. It determines comfort during training, security of fit during rolling, and IBJJF compliance. Three types are common:

Internal drawstring with wide elastic (recommended)

A wide elastic waistband with an internal drawstring provides the most secure fit for grappling. The elastic conforms to the body while the drawstring can be tightened for competition. No Velcro is used — fully IBJJF compliant. This is the standard construction for quality BJJ-specific grappling shorts.

Plush elastic with internal fixed waistband

A softer, wider elastic that sits flush against the skin — no rigid inner band. Very comfortable for training. Slightly less secure for high-intensity wrestling and takedown work where shorts may shift. Good for drilling-focused academies.

Board short waistband (with internal drawstring)

A stiffer, structured waistband similar to surfboard shorts — often paired with a drawstring. Durable and holds its shape well. Less comfortable against bare skin during long training sessions. More common in hybrid shorts designed for both training and casual wear.

Recommendation: Specify internal drawstring with wide elastic waistband for academy competition gear. This construction is comfortable, IBJJF compliant, and secure enough for all training and competition contexts.

Inseam length guide

Inseam length affects both comfort and IBJJF compliance. Getting this right prevents complaints after delivery.

Inseam length	Feel	Best for	IBJJF adult legal
9 – 10 inches	Short, MMA-style feel	MMA training, striking sports	No ❌
11 inches	Standard grappling length	Competition + training	Yes ✅
12 – 13 inches	Longer, more coverage	Guard-heavy training, comfort preference	Yes ✅
14+ inches	Very long — approaches knee	Specific preference only	Check — must not pass knee

Recommendation for most academies: 11 to 12 inch inseam. This covers IBJJF compliance for adult competitors and suits the majority of body types. If your student base skews taller, consider 12 to 13 inches as your standard.

Cost breakdown by order size — 2026

These are estimated per-unit manufacturing costs for fully custom sublimated grappling shorts on 100% polyester. Actual pricing varies by supplier, fabric choice, and waistband construction.

Order size	Estimated cost per unit	Notes
6 – 10 units	$30 – $38	Sample or very small team. Premium pricing. Good for quality testing a supplier.
11 – 20 units	$22 – $30	Small academy first order. Standard starting point.
21 – 50 units	$16 – $22	Mid-size academy. Good value per unit.
51 – 100 units	$14 – $18	Larger academy or annual blanket order.
100+ units	$12 – $16	Multi-location gym or combined kit order. Best pricing.

Grappling shorts are significantly cheaper per unit than gis and slightly cheaper than rash guards, making them the most cost-effective item in a complete no-gi kit. A complete kit (rash guard + shorts) in the 30 to 50 unit range typically costs $35 to $55 per set — manufactured cost — before retail markup.

Shipping costs for grappling shorts are lower than gis due to lighter weight and smaller volume. Budget 8 to 15% of the order value for international shipping.

Minimum order quantities

Grappling shorts have the most flexible MOQ options of all custom BJJ gear. Because the construction is simpler than a gi — no weaving, no collar, no belt loops — manufacturing can scale down more easily.

• 6 to 10 units: Available from many sublimation-focused suppliers. Premium per-unit pricing but good for small squads or quality testing.
• 10 to 20 units: The most common MOQ range for quality custom shorts. Per-unit pricing becomes commercially viable for most academies.
• 30+ units: Where volume pricing starts improving significantly. Ideal if ordering as part of a complete no-gi kit.

BJJ Sportswear handles custom grappling shorts from 10 units upward. Email export@fitmanpro.com with your size run and design details for a quote within 24 hours.

Matching shorts with your rash guards

The most important design decision for grappling shorts is colour consistency with your academy’s custom rash guards. A no-gi kit where the shorts and rash guard colours do not match exactly looks unprofessional on the mat — even if both items are individually well-made.

The only reliable way to guarantee colour matching is to order both items from the same supplier in the same production run.

Sublimation colour output varies slightly between different manufacturers and even between different production runs at the same manufacturer. Two suppliers can use identical Pantone colour codes and still produce slightly different outputs due to differences in ink, machine calibration, and fabric batch.

If you have already ordered custom rash guards from another supplier, ask them to produce your shorts as well. Provide your existing rash guards as colour reference samples. A professional supplier will calibrate their sublimation output to match.

See our custom rash guard ordering guide for the full rash guard specification — including the same fabric and sublimation recommendations that apply to matching shorts.

Design requirements — what to prepare

Grappling shorts design is generally simpler than rash guard design because the canvas is smaller. That said, the same file requirements apply.

Logo file

Vector format (AI, EPS, or SVG) is required. For sublimation printing, your logo will be incorporated into a full-garment design — your supplier’s design team will place it in approved zones (waistband panel, left or right leg panel). A high-resolution PNG at 300 DPI minimum is acceptable if vector is unavailable, but vector produces consistently sharper results.

Colour decisions

Decide on your base colour and accent colours. If you have existing rash guards or other academy gear, provide a physical sample or Pantone codes so the supplier can match exactly. Specify which colour goes on which panel — waistband colour, leg panel colour, and logo colour are all separate decisions.

Design zones

Standard grappling short design zones include:

• Waistband panel: A contrasting or matching colour band across the waistband — high visibility area
• Left and right leg panels: Primary design surfaces — logos, academy name, and graphics sit here
• Inseam panel: Often a contrasting colour for visual interest and a functional durability indicator
• Back panel: Sometimes includes academy name or design elements

Lead times — planning your order

Grappling shorts have the fastest production timeline of all custom BJJ gear — faster than gis and slightly faster than rash guards due to simpler construction.

Stage	Typical time	Notes
Quote and consultation	1 to 2 days	Fastest if logo file and size run are ready
Design mockup	3 to 5 days	Revisions add 2 to 3 days each
Your design approval	1 to 5 days	Most variable stage — depends on your review speed
Production	10 to 21 days	Varies by order size and supplier capacity
Quality inspection	1 to 3 days	Per-unit inspection before packing
Shipping	5 to 14 days	Air freight to most destinations
Total realistic timeline	3 to 6 weeks	Always add 1 to 2 weeks buffer

Planning rule: Order grappling shorts at least 8 weeks before any competition or event where you want students in matching kit. If ordering alongside rash guards in the same production run, use the rash guard timeline (5 to 9 weeks) as your guide — the combined order will move at the slower item’s pace.

Sizing guide for a mixed academy roster

Grappling shorts sizing is typically more straightforward than gi sizing — most suppliers use standard waist measurements (28, 30, 32, 34, 36, 38 inches) or general size tiers (XS through XXL). However, the same rules apply as with all custom gear:

• Use the supplier’s specific size chart. Do not rely on students’ self-reported sizes. A 32-inch waist in one brand may correspond to a “medium” or a “30” from a different manufacturer. Always map against the supplier’s specific measurements.
• Measure waist circumference, not clothing size. Ask each student to measure their natural waist at the level where they wear shorts. This eliminates the ambiguity of clothing size conventions across different countries and brands.
• Include youth sizes if your academy has a kids programme. Youth grappling shorts typically use age-based sizing (ages 6–8, 8–10, 10–12, 12–14) or waist-based sizing adapted for children’s proportions. Confirm your supplier’s youth range before ordering.
• Order 10% surplus. New students joining, size changes, and gear lost or damaged mean you will always need some surplus stock. 10% above your current roster count is a reasonable buffer for shorts.

5 questions to ask any supplier before ordering

1. “Are the shorts completely Velcro-free — including waistband, pockets, and any decorative elements?” The only acceptable answer is yes, with zero exceptions. If they cannot confirm this explicitly, your students risk IBJJF disqualification.
2. “What fabric and GSM are the shorts?” Expect: 100% polyester, 120–150 GSM for sublimation shorts. Vague answers like “high quality polyester” without a specific weight are a quality indicator red flag.
3. “What is the inseam length on your standard grappling short, and can it be customised?” Confirm it meets the IBJJF 11-inch minimum. Some manufacturers have a standard 9 or 10-inch inseam that requires customisation for competition compliance.
4. “Can you match the colour exactly to our existing rash guards if we send a sample?” A capable sublimation supplier can calibrate to match. If they say colour matching is approximate only, expect visible inconsistency between garments.
5. “What is your defect replacement policy?” Confirm in writing before ordering. Any professional supplier will replace defective units. “No refunds on custom orders” without a defect exception is an unacceptable supplier policy.

Pre-order checklist

• Confirmed Velcro-free construction — explicitly, not assumed
• Inseam length confirmed at 11 inches minimum for IBJJF-competing students
• Fabric specified — 100% polyester sublimation recommended
• Waistband type confirmed — internal drawstring with wide elastic recommended
• Logo file ready in vector format (AI, EPS, or SVG)
• Colour choices confirmed — Pantone codes or physical rash guard sample for matching
• Size run prepared — students measured against supplier’s specific size chart
• Youth sizes confirmed if academy has a kids programme
• 10% surplus stock planned above current roster count
• Delivery deadline confirmed — ordering minimum 8 weeks before the event
• Defect replacement policy confirmed in writing
• Retail pricing to students decided if running a pre-order

Common mistakes to avoid

• Ordering MMA shorts with Velcro instead of grappling-specific shorts — check every closure point
• Assuming inseam is IBJJF compliant — always confirm the measurement explicitly
• Ordering shorts from a different supplier than the rash guards — colour mismatch is almost guaranteed
• Using self-reported sizes instead of measuring against the supplier’s chart
• Not confirming the defect policy before production begins
