Long sleeve rashguard made out of 83% polyester and 17% elastane. The rashguard is printed with the Rebelz “R” in the front and Jiu Jitsu on the back. Both are made out of rubber print. Rubber print is elastic so it follows the fabric when stretched out. That way cracked print can be avoided. The fabric is solid black, this is to avoid the see thru effect when the fabric is stretched out. This Rebelz Rashguard Men Jiu Jitsu Long Sleeve is not at all basic, but still an essential in the jiu jitsu wardrobe. This style also comes with short sleeves. It also matches well with our Rebelz Spats Men Core and Rebelz Vale Tudo Shorts Men Core. Composition: 83% polyester and 17% elastane. Material weight: 200 gsm. Print technology: Rubber print.
