01 · Stone
Hyper-Cool Jade®
Jade stone milled to a powder and spun into the fiber. High thermal conductivity pulls heat off the skin: 3–5° cooler, 20× more breathable.

Made with jade stone and crab shells.
Two years at the raw-fiber level to put a stone, a shell and the world’s finest cotton into one yarn. Here is what’s inside, and why it matters.

The short version
Performance without plastic.
Most performance fabric is polyester — plastic, spun fine. Ours is Supima® cotton with jade and chitin written into the fiber itself. It does what synthetics do, without doing what synthetics do to you.

How it’s built
Three materials. One yarn.
Not a finish. Not a coating. The jade and the chitin go in at the fiber stage, so they are part of the thread for the life of the shirt. Scroll to open the yarn.
02 · Shell
Hyper-Chitin®
Chitin reclaimed from crab shells, bound to the fiber. Naturally antimicrobial: 99.9% fewer odor-causing bacteria, and it never washes out.

01Jade
It pulls heat.
Jade has been pressed to the skin for a thousand years because it feels cold. We ground it down and spun it into the fiber so the whole shirt does.
Hyper-Cool Jade® →02Chitin
It stays fresher.
Chitin is the structure of shell — porous, tough and naturally antimicrobial. Bound into the fiber it stops odor-causing bacteria before they start. Reclaimed from food waste.

03Cotton
It feels like a shirt.
Supima® is the long-staple American cotton that makes up less than 1% of the world’s supply. It’s why the fabric is soft on day one and still soft after the hundredth wash.
Shop by fabric →The difference
Written into the yarn. Not coated on.
Most “cooling” and “anti-odor” fabrics are polyester with a chemical finish sprayed on at the end. Finishes wash out. Ours can’t: the jade and the chitin are inside the fiber before it is ever knit.

What’s on your body is in your body.
Your skin takes in a good share of what sits on it. We think a shirt should list its ingredients the way food does. So here they are, next to the usual.
