Oxblood Serge, signed Rashu.
Every Rashu piece starts with a design built for the tatami: it reads from a distance, it holds up to washing, and it never gets in the way.
The piece

The story of the design
The Oxblood Serge design, its story
Oxblood, the Color of English Clubroom Leather
Oxblood, that deep blood-red, has long covered the leather of fine shoes and club armchairs. Oxblood Serge brings it onto the mat. The deep burgundy base carries a diagonal twill texture in the same shade, visible as the light moves across it. Black panels cut along the ribs slim the silhouette. A thin gold trim lines the collar and cuffs. On the back, a black yoke with a clean horizontal edge runs across the shoulders.
On the Mat
A sober, elegant piece for those who prefer class over noise. The burgundy is a change from the usual blacks without drawing every eye. It suits both regular classes and seminars.
Built for BJJ, no-gi, grappling, luta livre, and MMA. See also our BJJ rash guard, no-gi rash guard, grappling rash guard, and MMA rash guard selections.
What This Piece Changes in Training
- Against friction. The close-fitting fabric covers the skin: fewer mat burns, less friction against the gi or your opponent.
- Fast drying. The polyester and spandex knit wicks sweat and dries quickly between rounds.
- Stays in place under effort. Close fit and spandex: the piece moves with you without riding up or giving an opponent anything to grab.
- A print that lasts. Dyed deep into the fabric, the design becomes part of the fiber: it will not crack, peel, or feel rough, wash after wash.

Frequently Asked Questions
Which size should I choose?
Compression fit, very close to the body: order your usual size. Between 2 sizes, size up for a looser feel. The table above shows body measurements, not garment measurements.
Can I wear it under the gi?
Yes, for training. In IBJJF gi competition, a rash guard under the jacket is not allowed for men.
Can I wear it in competition?
Yes, at ADCC and in most grappling opens, where color is unrestricted. In IBJJF no-gi, the top must be black, white, or match your belt color: for that, choose a model from our ranked line.
When will I receive it?
Allow 7 to 10 days for tracked delivery. Shipping is $4.99, free from $80. Returns and size exchanges within 30 days.

The Oxblood Serge rashguard, answered
Another question? All the answers
What size for a close-fitting rashguard?
True to size, compression fit: take your usual size. Between 2 sizes, go up for more room, go down for a compression fit. The table gives body measurements, not garment measurements. Returns within 30 days, exchange at your cost unless defective.
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 the rashguard stay in place on the ground?
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 or under the gi.
