No-Gi Training Guide: BJJ Spats vs MMA Shorts

Walk into your first no-gi training class and the clothing question arrives before the first grip, shot or guard pass. Some athletes wear full-length BJJ spats under board-style shorts, others choose shorts alone, and some gyms allow compression leggings without an outer layer.

The right setup for no-gi training depends on three things: how you move, how much skin coverage you prefer, and what your academy or competition rules permit. BJJ spats offer close compression and full-leg coverage, while MMA or grappling shorts provide a looser outer layer with high durability around the hips and thighs.

MMA Short Vs Spats

For many athletes, the most practical no-gi training combination is a rash guard on top, BJJ spats underneath and grappling shorts over them. That is not the only workable option, however. Understanding what each garment does makes it much easier to build a kit that suits drilling, rolling, wrestling rounds and MMA sessions.

1. What to Wear for No-Gi Training

No-gi training uses close-fitting, snag-resistant sportswear instead of the traditional BJJ gi. A typical outfit combines a rash guard with grappling shorts, compression shorts or spats so the athlete can move without loose fabric, hard hardware or open pockets interfering with contact.

The main clothing demand in no-gi training is unrestricted movement. Scrambles involve hip rotation, knee flexion, guard retention, sprawls, inversions and fast direction changes. Gear that feels comfortable while standing can become restrictive once the athlete starts shooting, pummelling or working from seated guard.

A second consideration is coverage. Longer compression garments put a textile layer between the legs and the mat, while shorts leave more skin exposed but usually feel cooler. Neither choice automatically makes training better; the useful question is which balance of coverage, heat management and freedom suits the athlete.

Dress codes also matter. Everyday academy rules are set by individual gyms, while tournament clothing is governed by the organiser. Athletes preparing for competition should review the current IBJJF No-Gi uniform requirements or the rules of the specific event rather than assuming that normal class clothing is competition legal.

2. BJJ Spats for No-Gi Training

BJJ spats are stretch compression leggings designed for grappling movement. During no-gi training, they sit close to the body from the waist through the ankle, reducing loose fabric while maintaining coverage across the thighs, knees and lower legs.

Most spats use polyester-elastane (spandex) or nylon-elastane (spandex) performance fabrics. The stretch component lets the garment follow deep hip and knee positions, while the knitted synthetic base gives the fabric enough recovery to return towards its original shape after repeated extension.

For no-gi training, the biggest practical advantage is continuous leg coverage. Athletes who spend significant time playing guard, wrestling from the knees or drilling takedowns often prefer having fabric between their skin and the mat. Spats also create a smooth base layer beneath grappling shorts.

When BJJ Spats Work Best

BJJ spats suit no-gi training particularly well when an athlete values a close fit and full coverage. They are common in submission grappling, wrestling-style practice, conditioning sessions and technical drilling where freedom through the hips matters more than a loose silhouette.

• Full-leg coverage for mat-based drills and rolling
• A close fit that reduces loose fabric during no-gi training
• Four-way stretch when suitable elastane blends are used
• A smooth base layer under MMA or grappling shorts
• Comfort for athletes who prefer compression-style apparel

Fit matters more than simply choosing the tightest size. Spats for training should stay at the waist and ankle without excessive bunching, but the fabric should not create strong pulling across the crotch, knees or calves. If the waistband rolls repeatedly or the seams twist during squats, the pattern or size is wrong for the wearer.

3. MMA Shorts for No-Gi Training

MMA shorts used for training are lightweight combat-sport shorts built to tolerate grappling, wrestling and striking movement. In this guide, the term includes board-style MMA shorts and dedicated grappling shorts with safe closures and no exposed hard components.

Compared with ordinary gym shorts, a purpose-built pair should provide a secure waistband, enough room through the seat and thigh, and stretch where the pattern needs it. No-gi training constantly loads the side seams and crotch through lunges, sprawls and guard work, so construction quality matters as much as fabric weight.

Good grappling shorts also avoid details that can catch fingers or scratch a partner. Open pockets, exposed zippers, metal hardware and dangling drawcords have no useful role in close-contact training. Competition organisations can impose their own specific restrictions, so training shorts are not automatically tournament compliant.

Why Athletes Choose MMA Shorts

Many practitioners choose MMA shorts for no-gi training because the loose outer layer feels familiar and works across several combat sports. The same well-designed pair can move from BJJ drilling to wrestling rounds or MMA pad work without requiring a completely different lower-body setup.

• Lightweight coverage across the hips and upper legs
• Durable woven fabric for repeated no-gi match
• Side slits or stretch panels for greater stride length
• Secure waist construction for scrambling and takedowns
• Compatibility with compression shorts or BJJ spats underneath

Short length should allow the athlete to squat and lift the knee without the hem binding against the thigh. For no-gi match, a cut that is too long can catch around the knee, while an excessively wide leg can create more fabric for hands and feet to encounter during scrambles.

4. BJJ Spats vs MMA Shorts for No-Gi Training

BJJ spats and MMA shorts solve different clothing problems in training. Spats prioritise close fit and leg coverage; grappling shorts prioritise a durable outer layer, airflow and a more relaxed silhouette.

Neither garment wins every comparison. Someone who overheats easily during no-gi training can prefer shorts alone, while an athlete who dislikes bare knees and shins against the mat can prefer spats. Frequent competitors also need to separate personal comfort from the uniform specification of the event they enter.

5. Should You Wear Spats and Shorts Together for No-Gi Training?

Wearing BJJ spats under grappling shorts is one of the most versatile setups for no-gi training. The spats provide close full-leg coverage, while the shorts add an outer layer around the waist, hips and upper thighs.

This combination is useful for athletes who move between BJJ and MMA-style sessions. It retains the stretch and coverage of compression apparel without giving up the feel and durability of combat shorts. During long no-gi training sessions, however, two layers also retain more heat than shorts alone.

Layering works best when both garments have compatible patterns. If the spats have a thick waistband and the shorts use another bulky waist construction, the doubled area can feel uncomfortable during guard work. For no-gi training, flatter waistbands and low-profile internal seams generally sit more comfortably beneath an outer layer.

A Complete No-Gi Training Outfit

• A close-fitting rash guard for the upper body
• BJJ spats or compression shorts as the base layer
• Pocket-free MMA or grappling shorts as the outer layer
• Clean training apparel for every no-gi training session

Beginners do not need to buy every possible garment immediately. Start with the academy’s required no-gi training kit, learn what feels comfortable during live rounds, then add spats or a second pair of shorts once your weekly training volume increases.

6. Academy Dress Codes and No-Gi Training Competition Rules

What is acceptable for no-gi training at your academy is not automatically legal in competition. Gyms set their own class dress codes, while tournament organisers specify permitted colours, garment lengths, closures and other details.

Under the current IBJJF No-Gi uniform requirements, both genders wear a skin-tight elastic shirt that meets defined colour requirements. For men, permitted board shorts must meet rules covering colour, length, pockets and hard closures; compression shorts can be worn beneath them. Women have separate provisions covering shorts, compression shorts and skin-tight spats. Athletes should check the current IBJJF rule resources before entering an event.

That distinction matters because an athlete can train comfortably in spats alone at one gym but need a different configuration for a particular tournament. Build your no-gi training wardrobe around normal practice first, then keep a separate competition-legal set if you regularly compete.

7. How to Choose the Right No-Gi Training Gear

The best no-gi training gear matches the athlete’s movement, climate, training frequency and rules rather than simply following the most popular look. Fabric, pattern engineering and seam construction determine how the garment behaves once drilling becomes live grappling.

Choose BJJ Spats If You Prefer More Coverage

Choose spats for no-gi training when you like full-leg coverage, a compression fit and minimal loose fabric. Look for a waistband that stays stable, sufficient four-way stretch and seams positioned away from high-friction pressure points.

Choose MMA Shorts If You Prefer a Looser Feel

Choose grappling shorts for no-gi training when you want more airflow around the legs, an adaptable outer layer or apparel that can also work in MMA and wrestling sessions. Inspect the crotch construction, side seam reinforcement and waistband before focusing on graphics.

Choose Both for a Flexible Weekly Setup

Choose both when your no-gi training week includes different intensity levels or combat disciplines. Wearing spats underneath shorts gives you the option to keep full coverage without relying on compression leggings as the visible outer garment.

Fabric quality becomes more important as no-gi training frequency rises. A garment worn several times each week faces repeated sweat, washing and stretch cycles, so stable recovery and secure stitching matter more than they do in occasional gym wear.

8. How to Care for Apparel After No-Gi Training

No-gi training clothing should be cleaned after every use and never left damp in a gym bag for long periods. Close-contact sports involve repeated skin contact and shared surfaces, making apparel hygiene part of normal training discipline.

The CDC guidance for athletes recommends showering after exercise, not sharing personal items and washing clothing after use. These habits are particularly relevant to no-gi training because grappling involves extensive skin-to-skin contact and contact with shared athletic surfaces.

The CDC guidance on ringworm and athletes also identifies contact sports, excessive sweating and shared surfaces or equipment as relevant exposure factors. After no-gi training, follow the garment’s care label and make sure the kit is clean and dry before packing it again.

• Wash spats, shorts and rash guards after every no-gi training session
• Follow the care label for wash temperature and drying method
• Do not leave wet apparel sealed inside a training bag
• Check seams, waistbands and printed areas for wear
• Keep a second kit if you train again before the first set is clean and dry

9. Custom No-Gi Training Sportswear for Gyms and Brands

For BJJ academies, MMA gyms and private-label brands, no-gi training apparel works best as a coordinated system rather than a collection of unrelated pieces. Rash guards, spats, compression shorts and MMA shorts can share colours, graphics, logos and fit standards while serving different training needs.

Product development should start with the intended athlete and activity. A competition-focused no-gi training collection has different priorities from a lifestyle range or an MMA gym uniform. Fabric weight, stretch percentage, waistband construction, seam placement and decoration method all need to match the product brief.

For B2B buyers, sampling is especially important because compression pieces and combat shorts behave differently under movement. A no-gi training sample should be tested through squats, sprawls, hip rotation, guard positions and repeated stretching rather than approved only from photographs.

Customisation can then be built around the academy or brand identity. A complete no-gi training collection can coordinate rash guard graphics, waistband details, club logos, sponsor placements, colour systems and private labels without forcing every product to use identical fabric or construction.

10. Final No-Gi Training Gear Takeaway

There is no single lower-body garment that suits every athlete in no-gi training. BJJ spats provide close compression and greater leg coverage, while MMA shorts offer a looser, durable outer layer that works well across grappling and mixed combat-sport sessions.

For many practitioners, wearing both gives the most flexible no-gi training setup. For others, shorts alone feel cooler and simpler. Your academy’s dress code, competition rules, climate and personal comfort should decide the final combination rather than appearance alone.

If you are developing custom rash guards, BJJ spats, MMA shorts or a complete no-gi training range for a gym, team or sportswear brand, Tonton Sportswear can support the project from design and fabric selection through sampling and bulk manufacturing.

Tonton Sportswear provides physical samples so buyers can review fit, stretch, construction and artwork before full production. Testing your no-gi training apparel as a real garment gives your team a much clearer standard for the final bulk order.

11. Frequently Asked Questions About No-Gi Training Gear

Can You Wear BJJ Spats Without Shorts for No-Gi Training?

Some academies allow spats alone for no-gi training, while others require shorts over compression clothing. Ask your coach about class policy, and check the organiser’s current uniform rules separately if you are preparing for competition.

Do BJJ Spats Help With Mat Burn During No-Gi Training?

Spats create a textile layer between the legs and the mat, reducing direct skin contact with the surface. They do not eliminate every friction injury, but athletes who prefer more coverage often find them useful during no-gi training.

Are MMA Shorts Different From Normal Gym Shorts?

Yes. Shorts designed for no-gi training generally use safer, more secure construction for grappling, with reinforced seams, controlled stretch and waist systems intended to stay in place during contact. Ordinary gym shorts can include pockets, zippers or loose details that are unsuitable for close grappling.

Should Beginners Buy BJJ Spats or MMA Shorts First?

For many beginners, dedicated grappling shorts are a practical first purchase for no-gi training because they work as a stand-alone lower-body garment. Add spats when you want more leg coverage, compression or an additional layer for frequent sessions.

What Is the Best Complete Outfit for No-Gi Training?

A common no-gi training setup combines a fitted rash guard with grappling shorts and either BJJ spats or compression shorts underneath. The best version is the one that fits securely, allows full movement and complies with your academy or competition rules.
