The story of the design

Mecha: the story behind the design

A Printed Exoskeleton, a Reactor on the Back

Giant robots and exoskeletons have fed science fiction for decades: the machine as an extension of the fighter. Mecha prints that idea across the whole top. Steel-grey armor plates, drawn with their panel lines, cover the torso, punctuated by orange warning stripes. Down the sleeves, exoskeleton pistons follow the arm. On the back, a reactor core glows orange between the shoulder blades. Everything is printed flat: the armor is a graphic illusion.

On the Mat

A design built for those who move forward like a machine: constant pressure, steady rhythm, no retreat. The steel grey stays understated, and the orange signals every movement. It fits right in both MMA and grappling.

Built for no-gi, grappling, luta livre, and MMA. See also our 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.

Another question? All the answers

How do I choose my size?

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.

Caring for your rash guard

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.
