Features

Performance Fabric
Soft polyester-elastane performance fabric with 4-way stretch, quick-drying properties, and moisture management for active training.

Fabric composition may vary depending on where your order is produced:

  • 78% polyester, 22% elastane — US/Mexico
  • 84% polyester, 16% elastane — Latvia

Raglan Construction
Raglan sleeves extend to the collar, creating diagonal seams that support natural shoulder movement.

Extended Coverage
The longer body and sleeves provide added coverage during grappling and under-gi wear.

Smooth Interior
Flat seams and coverstitch construction help keep the interior smooth against the skin.

All-Over Sublimation
The artwork is dyed into the fabric rather than applied as a surface layer, helping reduce the cracking and peeling associated with surface-applied graphics.

Because the design is sublimated onto white fabric, dark areas may appear slightly lighter when stretched, and small amounts of the white base fabric may be visible at seams or folds. This is a normal characteristic of the all-over sublimation process.
About the BJJ KATAKANA Rash Guard

Built for the Mats
The SPARS Men's BJJ KATAKANA Long-Sleeve Rash Guard is designed in Japan for grappling and Brazilian Jiu-Jitsu training. Its fitted athletic cut and smooth 4-way stretch fabric move with you through drilling and rolling, while layering comfortably under the gi.

The Design
The chest graphic pairs the off-white 「ジュウジュツ」 — the Japanese katakana rendering of "Jiu-Jitsu" — with BJJ. Rather than being typeset in a standard font, the lettering is hand-drawn with a manga-inspired style, using intentionally uneven balance, tilted forms, and extended strokes.

Kuzushi (崩し) is the grappling principle of disrupting an opponent's balance to create an opening. That same idea is applied to the letterforms themselves: off-balance, yet unmistakable.

The off-white SPARS logo and wordmark are centered below the back collar for a clean, restrained finish.

Japanese Color Names
Each SPARS color is named after a traditional Japanese color. Iron Black — Tetsuguro (鉄黒) is a deep, subdued black associated with iron, chosen to reflect the brand's Japanese roots while keeping the look restrained for regular training.

Training Use
This rash guard is designed for regular grappling and BJJ training. Competition eligibility depends on the event, division, and uniform rules. Check your event’s requirements before competing.
