The short version

Side by side

The polyester standard
The V1
Odour 01
Poly The funk gets into the plastic and stays. A normal wash can't shift it, so it's permanent.
V1 Releases odour instead of trapping it. One ordinary wash and it resets, month after month.
Round three 02
Poly Plastic doesn't breathe, so you cook in it. A wet shell by the third round.
V1 Natural fibre breathes. You stop noticing you're wearing it.
On your skin 03
Poly PET. The same polymer as a drink bottle, skin-tight under heat and friction every round.
V1 Over 90% natural fibre. Nothing plastic pressed against you the whole session.
Movement 04
Poly Compression-tight. You're aware of it the whole session.
V1 Stretches where you move. Shoot, scramble, reach, and nothing pulls back.
Toughness 05
Poly Holds up. Nobody's arguing it doesn't.
V1 270gsm, reinforced sport stitching, silicone gripper hem that stays down. Same fight, no plastic.
Off the mats 06
Poly Loud print, big branding. It announces the sport, so it only works where the sport is.
V1 Tonal branding, nothing shouting. A second skin you forget you're wearing, and it goes everywhere you do.
Same weight class. Different starting material.
One layer, many lives

Built for the scramble. Worn everywhere else.

The bar was full-stretch grappling on soaked skin. Clearing it made a layer that holds up anywhere: second-skin fit, breathes in the heat, stays fresher for longer.

01
Fight

The job it was designed for. Full-stretch patterning, gripper hem, nothing plastic against your skin.

02
Run

Breathes in the heat instead of turning into a wet shell.

03
Gym

Second-skin stretch and breathability through every rep, session after session.

04
Everyday

Fresh enough to wear from the session into the rest of your day.

Over 90% natural fibre. The 8% that isn't is what keeps it athletic.

What it's made of, and why

  • Bamboo Viscose

    Breathes, and releases odour instead of trapping it, so a wash actually resets it.

  • Organic Cotton

    The backbone. Holds the build together, and holds the shape.

  • Elastane

    The compromise we kept. Nothing natural recovers its shape like this, so we used as little as the job takes.

Frequently Asked Questions

True to size, unisex, and made to sit tight. If you're between sizes, go down one. Judge fit by chest and torso width, not length. For women, YM to S is the usual pick.

Polyester keeps what sweat leaves behind. That's why the funk survives normal detergent and people end up buying specialist sport washes. Natural fibre releases it in an ordinary wash: you wash it, it resets. The whole shirt is built around that difference.

The V1 is a 270gsm heavyweight, the same weight class as the polyester rashguards you already own, with reinforced sport stitching and a silicone gripper hem. It's built for grip and pull.

That's half the point. It's cut for grappling, and it wears as a base layer for everything else: the run, the gym, the hike, the rest of the day. It breathes and stays fresher for longer, so it doesn't live in the gym bag.

Yes, that's a classic job for it. It's cut to sit tight as a base layer, and the silicone gripper hem stays tucked through grip and pull.

Yes, as long as the event doesn't require ranked rashguards. Always check your competition's ruleset (and your division) to confirm colour and uniform requirements before competing.

64% bamboo viscose, 28% organic cotton, 8% elastane for stretch. The fabric is certified to OEKO-TEX® STANDARD 100, Class I, the class used for baby clothing.

Cold machine wash on gentle, hang it to dry. No tumble dryer, no bleach, no iron, no dry cleaning. Ordinary detergent is the point: you never need a specialist wash to bring it back to neutral.
