I did not own a pair of spats for my first three years of no-gi training. I rolled in board shorts and a rash guard like everyone else at my gym, and it was fine until the winter my knees started aching every time the heat in our gym dropped below what the building’s owner wanted to pay for. A training partner who competes handed me a pair of his backup spats one cold Tuesday and I have not gone back to bare-leg no-gi since.

What BJJ Spats Actually Are, and What They Are Not

Spats are full-length compression leggings, usually a polyester-spandex blend, built specifically for grappling. That is a narrower category than it sounds. They are not the same product as a pair of running tights, and they are not the bottom half of a rash guard set — most rash guard tops are sold alone, and the “bottoms” that pair with them are usually board shorts, not spats.

The difference that matters on the mat: spats cover your entire leg in a smooth, seam-flat fabric designed to resist grip and abrasion. Running tights bag at the knee within a few rolls and were never stitched to survive someone pulling a heel hook. Board shorts leave your shins and calves bare, which is the exact surface spats exist to cover.

Do You Actually Need Them?

Not everyone does. If your gym is warm, you train gi more than no-gi, and you have not had a mat rash or a cold-knee problem, board shorts and a rash guard cover you fine. Spats earn their spot in your bag for a few specific situations:

• Cold gyms. Compression fabric holds a little more warmth around the knees and ankles, which older joints notice more than 22-year-old ones do.
• Frequent no-gi rounds. Bare shins and calves against a mat that a dozen other people used that day is a hygiene bet you are making every single round. Spats cut that exposure a lot.
• Rolling with grip-heavy partners. Bare skin is easier to grab and control than compression fabric. It is a small edge, not a big one, but it is real.
• Competition. Most no-gi rulesets require full leg coverage, so spats are not optional there regardless of preference.

What to Look For in a Pair

Four things separate a pair of spats that lasts a season from one that is see-through by month two.

• Compression fit, not loose. A baggy pair bunches at the knee and gives an opponent something to grab, which defeats the point.
• Flatlock or bonded seams. Regular sewn seams rub raw during long mat time. Look for “flatlock” or “seamless” in the product description.
• Ankle cuff, not just a hemmed edge. A proper cuff keeps the leg from riding up mid-roll. This sounds minor until you are re-adjusting your pants during a scramble.
• Fabric weight. Thicker fabric survives longer and resists see-through wear, but it is also warmer — worth thinking about if your gym already runs hot.

Best BJJ Spats for No-Gi Training in 2026

Three price tiers, all built specifically for grappling rather than general athletic wear.

• Elite Sports Men’s BJJ Spats — the budget entry point at around $20. Compression fit, flat seams, does the job for someone testing whether spats are worth adding to the bag at all before spending more.
• Venum G-Fit Air Spat — the pair I would tell most people to buy. Venum’s grappling line uses a lighter, more breathable weave than their MMA-training gear, which matters if your gym runs warm, and the compression holds shape after repeated washing better than the budget tier.
• Hayabusa Jiu-Jitsu Compression Spats — the durability pick. Heavier fabric, reinforced stitching at the knee and seat, built for someone training five or six times a week who wants one pair that outlasts a full season rather than replacing a cheaper pair twice.

I have not personally worn all three long enough to rank them on longevity, so treat the tiering above as a buying framework based on build and price, not a head-to-head durability test.

Spats vs Rash Guard Bottoms vs Board Shorts

These three get lumped together and they are not interchangeable. If you already have a full no-gi kit sorted out, our complete no-gi kit checklist covers the whole picture — rash guard, shorts, mouthguard, the works. The short version on bottoms specifically:

• Board shorts are the default and the cheapest option. Bare shins and calves, loose fit, no grip resistance.
• Rash guard bottoms are less common — most rash guards are sold as a top only, paired with board shorts or spats underneath, not a matching bottom. If you are shopping for tops, our rash guard buying guide covers the top half of this decision.
• Spats are the only one of the three built for full-leg coverage and grip resistance specifically.

Caring for Spats So They Do Not Become a Problem

Spats sit against your skin for the entire round, longer than a rash guard top touches most of your torso, which makes the hygiene math less forgiving. Wash after every single session, not every other one. If you have ever dealt with a stubborn skin issue on the mats, our guide on preventing ringworm in BJJ and our roundup of antibacterial body wash options both cover the routine that actually works, and spats are exactly the kind of gear that routine is built around.

Frequently Asked Questions

Can I wear running leggings instead of buying grappling spats

You can for a session or two, but they are not built for it. Running tights are designed for stretch during a stride, not for someone gripping and pulling the fabric during a scramble, so they tend to tear at the knee or waistband faster than a pair made for grappling.

Should BJJ spats fit tight or loose

Tight. A compression fit is the point because it gives a partner less loose fabric to grab, and it reduces the chance of the leg riding up mid-roll. If a pair feels baggy at the knee out of the package, size down or pick a different brand.

How often should I wash my spats

After every session, every time, no exceptions. Spats spend more time in direct skin contact with mats than almost anything else in your bag, and skipping a wash is exactly how minor skin issues get a foothold.

Do I still need spats if I already wear a rash guard

Yes, they cover different body parts. A rash guard top and a pair of spats are the full coverage combination, and one without the other still leaves either your legs or your torso exposed to the mat.

Bottom Line

If you train no-gi more than occasionally, spats are one of the cheaper upgrades in your bag that actually changes how a session feels: warmer joints, less bare-skin mat contact, one less thing to think about mid-roll. Start with the budget tier if you are not sure it is for you, and move up once you know spats are staying in your bag for good. For the rest of your no-gi setup, our no-gi kit checklist has you covered, and if you are training with any of the aches that come with rolling past 35, the BJJ after 40 hub is where I keep everything on that.
