Ce que raconte le rash guard Octagon Short-Sleeve - Men
L'octogone est devenu l'image même du MMA : 8 côtés, un grillage, 2 combattants. Ce design transforme cette cage en motif graphique. Le grillage en losanges est tracé en lignes acier sur un fond noir, sans effet ni décor autour. Dans le dos, la forme de l'octogone encadre tout le dos, comme une arène vue du dessus. Une pièce graphique, brute et lisible.
Pensé pour le no-gi, le grappling, la luta livre et le MMA. Voir aussi nos sélections rashguard no gi, rashguard grappling et rashguard MMA.

What size should I take for this compression top?
True to size, compression fit: take your usual size. Between two sizes, go up for more room, go down for a compression fit. The table gives body measurements, not garment measurements. Returns and size exchange within 30 days.
Does the design hold up in the wash?
Yes: the design is printed into the fibre, with no surface coating. It won't crack or come off in the wash. Wash at 30°C maximum, inside out, with no fabric softener, and air dry.
Does it shift during rolls?
Cut: fitted, with 12% spandex. The piece follows your movement without flapping or giving anyone a grip. Fitted to your size, it stays close to the body.
Rash guard or compression tee?
The rash guard carries the design across the whole surface, from collar to wrists. It protects the skin from friction and mat burns in no-gi BJJ, grappling and MMA.
The compression tee is plain and understated: one colour, the Rashu badge. It supports the muscles and can be worn on its own for training or under the gi.
Same 230 g/m² fabric, 4-way stretch, flat seams, same size guide. Compression tees
