Your shorts slipped mid-roll. You stopped, adjusted, and gave up the position. It’s one of those small things that shouldn’t happen — and doesn’t have to.
The best BJJ shorts for training have a secure waistband (drawstring plus velcro), four-way stretch fabric, and a split hem at the leg. Board shorts work for beginners. Hybrid grappling shorts handle heavy drilling without moving. Pro grappling shorts lock in for competition. The difference comes down to three details — and you can test all three before you buy.
- A drawstring-only waistband slips. You need velcro too — two points of contact.
- Four-way stretch lets your hips rotate fully without the shorts catching mid-movement.
- Split hems stop the “shorts tug” during shots and guard step-throughs.
What Actually Makes Training Shorts Work?
Not every athletic short belongs on a BJJ mat. Most don’t.
Regular gym shorts catch on your partner’s knees during guard passes. Board shorts bunch under pressure in leg locks. Running shorts ride up on every hip escape. If you’ve trained in any of these and wondered why you’re always adjusting — that’s why.
Three things separate a training short from a distraction:
1. Waistband security. A drawstring alone isn’t enough. Add velcro and the waistband holds through leg triangles, guard passes, and double-leg shots. Without velcro, you’ll spend rounds adjusting instead of training.
2. Four-way stretch. Shorts that only stretch side-to-side pull tight when you move vertically — bridging, shooting, posting a knee. Four-way stretch is the minimum. Feel the fabric with a stretch test before committing.
3. Split hem. The vent at the bottom of each leg isn’t decorative. It lets you step through a guard or shoot without the shorts pulling against your leg. Tiny feature. Big difference after an hour of rolling.
The 3 Best Types of BJJ Training Shorts
Match the type to how you train:
| Type | Waistband | Stretch | Best For | Shop |
|---|---|---|---|---|
| Board Shorts | Drawstring only | Low–medium | Beginners, casual no-gi | Shop on Amazon |
| Hybrid Grappling | Drawstring + velcro | 4-way (high) | Most grapplers — all-round pick | Shop on Amazon |
| Pro Grappling | Full velcro panel | Ultra-high flex | Competition, heavy drilling | Shop on Amazon |
For most people starting no-gi: hybrid is the move. You don’t need to spend more than basic board-short pricing — but you’ll train more and adjust less. The velcro waistband alone is worth it.

The Stretch Panel Test (Try This Before You Buy)
Here’s the thing nobody mentions when you’re browsing training shorts online.
Grab the shorts at both thighs. Pull side to side. Then pull front to back. If the fabric snaps back clean both ways without puckering, that’s four-way stretch. If it resists or bunches in one direction, it’s single-direction stretch — and you’ll feel that on every hip escape for the rest of your training life.
Wrestling coaches call this the “gear freedom” check. Gear that restricts your range of motion slows you down more than technique alone can fix. In wrestling, the singlet is formfitting for exactly that reason — nothing between you and movement. In no-gi BJJ you can’t go that tight, but the principle’s the same. Your shorts should disappear when you’re rolling.
A lesson from judo: grip security matters more than most beginners expect. A lapel grip slips under pressure; a reinforced collar grip holds. The same logic applies to your waistband. Velcro is the reinforced grip.
And while you’re thinking about gear that holds together under pressure — the same principle applies to your gi. Check out the Stylso men’s gi on Amazon if you train both gi and no-gi.
Getting the Right Fit
Measure your natural waist — the narrowest part of your torso, not your hips.
| Waist | Short Size |
|---|---|
| 28″–30″ | XS |
| 30″–32″ | S |
| 32″–34″ | M |
| 34″–36″ | L |
| 36″–38″ | XL |
| 38″–40″ | XXL |
When you’re between sizes, go up. You want a half-inch of breathing room at the waistband when standing — the split hem handles the leg length. And when in doubt about your no-gi setup, the best no-gi shorts guide has a full breakdown of what to look for.
One Adjustment That Fixes Everything
Wrestlers crossing into BJJ often say training shorts feel strange at first. In wrestling, the singlet gives a snug anchor. In no-gi, the shorts float.
The fix is simple: cinch the drawstring snug first, then close the velcro flat over it. Two points of contact. Once you’ve done that, the shorts anchor and stop being a distraction — and you can focus on actually training.
Most beginners skip this. Most experienced grapplers do it automatically. Now you know.

FAQ
What’s the difference between BJJ shorts and MMA shorts?
MMA shorts often have a looser cut and less stretch. BJJ training shorts are built specifically for grappling — tighter waistbands, split hems, and four-way stretch panels for full hip mobility on the mat.
Can I use regular gym shorts for BJJ training?
You can, but they’ll catch on your partner’s knees and bunch during ground work. They also won’t stay up through leg locks. Training shorts built for grappling are worth it after even one session.
How do I know what size BJJ shorts to get?
Measure your natural waist in inches and use the chart above. When in doubt, size up — you want room to move, not a tight waistband under a guard pass.
Do BJJ training shorts need pockets?
Not for training. Pockets catch fingers and create grips your partner shouldn’t have. Purpose-built grappling shorts skip them.
What fabric is best for BJJ training shorts?
Polyester-spandex blends (typically 85–95% polyester, 5–15% spandex) give the best stretch, durability, and sweat management. Cotton holds water and catches — avoid it.
How do I keep my shorts from slipping during training?
Cinch the drawstring snug first, then close the velcro flat. Two points of contact. Works every time.
Can I wear BJJ training shorts for wrestling or submission grappling?
Yes. Waistband and stretch requirements are almost identical. Just check for metal in the closure — some competition rulesets prohibit it.
