What to Wear to a BJJ Open Mat β€” Men's Complete Guide

Walking onto the mats for a weekend Brazilian Jiu-Jitsu open mat or high-level no-gi grappling seminar immerses you in an intense community of practitioners drilling sweeps, guard passes, and submissions. Gripping canvas kimonos or scrambling through high-friction no-gi rounds under heavy gym humidity demands hygienic, tear-resistant compression apparel that protects your skin and moves seamlessly.

The benchmark dress code is technical combat sport grappling wear: snug moisture-wicking compression rashguards, flat-seam grappling spats beneath drawstring board shorts, and clean slip-on recovery slides for walking off the mats. Hardware-free athletic gear prevents painful mat burns while ensuring you never scratch training partners during close-contact groundwork transitions.

From mat hygiene etiquette and hardware-free shorts to sweat-wicking compression layers and post-roll warmth, here is your definitive blueprint for Brazilian Jiu-Jitsu open mat style.

Outfits that work

Do

  • βœ“Wear snug flatlock-stitched compression rashguards that protect your skin against friction mat burns.
  • βœ“Choose drawstring board shorts with zero exterior metal zippers, snaps, or plastic hardware pockets.
  • βœ“Wear compression spats underneath your shorts to reduce skin abrasion and bacterial mat transmission.
  • βœ“Slip into clean slide sandals or shower slides the moment your feet leave the matted training area.
  • βœ“Pack a warm fleece hoodie and dry cotton sweatpants for a comfortable post-training recovery commute.

Don't

  • βœ—Avoid loose cotton t-shirts that stretch out, trap fingers and toes, and become heavy with sweat.
  • βœ—Don't wear shorts with exposed metal zippers, plastic aglets, or velcro loops that scratch partners.
  • βœ—Avoid walking barefoot on dirty locker room or bathroom floors before stepping back onto live mats.
  • βœ—Don't wear rings, watches, chains, or piercing jewelry that can dislodge or tear skin during rolls.

Style tips

The Zero-Hardware Combat Rule

Grappling involves tight body-to-body contact and intense friction. Board shorts must feature internal flat drawstrings and seamless construction to eliminate sharp edges that could lacerate an opponent's face or catch toes.

Rashguard Compression and Hygiene Defense

High-density polyester-spandex compression shirts create an essential barrier against ringworm and mat germs. Moisture-wicking textiles also keep your body cooler during ten consecutive six-minute sparring rounds.

Mat-to-Street Slide Discipline

Martial arts academies strictly prohibit shoes on mats and bare feet off mats. Having durable slip-on slides right at the mat edge keeps training areas spotless while simplifying transition back to street clothes.

What to Wear to a Rag Papermaking Class β€” Men's Complete Guide

Standing before a deep wooden vat of beaten cotton linters and abaca pulp for a handmade papermaking workshop immerses you in roaring Hollander beaters, brass-wired hardwood moulds, and wet wool felts. Papermakers plunge mesh moulds and deckles into cloudy pulp slurry, shake the frame to interlock cellulose fibers, and couch wet sheets onto damp felt post stacks.
