Built for the Mats
The SPARS Men's BJJ KATAKANA Long-Sleeve Rash Guard is a Japanese-designed Brazilian Jiu-Jitsu rash guard built for regular training.

Smooth 4-way stretch fabric moves with you through drilling, positional work, and rolling, helps manage moisture, and layers cleanly under the gi. Made for the hours you actually put in on the mats.

The Design
The SPARS BJJ KATAKANA chest design pairs bold off-white 「ジュウジュツ」 — the Japanese katakana rendering of “Jiu-Jitsu” — with BJJ on the chest, hand-drawn in the manga lettering tradition rather than typeset in a standard font.

The characters are deliberately off-balance: tilted, with some strokes stretched far beyond their normal length. Kuzushi (崩し) is the grappling principle of disrupting an opponent's balance to create an opening. Here, that same idea is applied to the letterforms themselves.

Off-balance, yet unmistakable.

On the back, the SPARS logo and wordmark sit centered below the collar for a clean, restrained finish.

The Fit
A fitted athletic cut with raglan sleeves that extend to the collar, creating diagonal seams that support natural shoulder movement during grappling.

The body and sleeves are cut longer than a standard tee to provide additional coverage and help the garment stay in place when you're moving, scrambling, or training under a gi. Flat seams and coverstitch construction help keep the interior smooth against the skin.

Available in XS through 3XL.
This item runs small. If your measurements fall between sizes, or if you prefer a slightly less compressive fit, we recommend sizing up.

Iron Black — Tetsuguro
Finished in Iron Black — Tetsuguro (鉄黒) with the BJJ KATAKANA chest design and SPARS back lockup in off-white.

The design is produced using all-over sublimation, which dyes the artwork into the fabric rather than applying it as a surface layer. This helps avoid the cracking and peeling associated with surface-applied graphics while maintaining the smooth feel of the garment.

Made for the BJJ Life
For hobbyists, coaches, gi practitioners, no-gi grapplers, and competitors.

Built for regular training sessions, drilling, rolling, and open mat, and cut to wear comfortably under the gi.

• Wash promptly after training to remove sweat, and avoid leaving the garment damp in a gym bag for extended periods.
• Machine wash cold, inside-out, on a gentle cycle with mild detergent and similar colors.
• Do not use fabric softener, as it can coat synthetic fibers and reduce moisture-wicking performance.
• Do not bleach.
• Hang-dry for longest life, or tumble dry low.
• Avoid high heat, which can damage elastane.
• Avoid prolonged contact with hook-and-loop fasteners and rough surfaces, which may pull fibers from the fabric.
• Cool iron inside-out only if necessary. Do not iron the printed surface directly.
• Do not dry clean.
