Tap a colour to see it. Open a piece for sizes and the full details. Buy takes you to Printify to pay. Made when you order it. Once a collection closes it is not reprinted.









We hold our research to a standard. The clothes get the same treatment — heavy cotton, honest stitching, nothing we would not wear ourselves.
Why Function
Every piece and every colour, photographed in the places we actually wear them.

FNCTN RnD Supply is the apparel side of FNCTN RnD. We started it for the early mornings and the days nobody is watching. The work that gets you anywhere is rarely the part anyone sees.
Every collection runs once. 001 is open now. When a collection is retired we never print it again, so the piece you own stays yours.
To function well you have to be consistent. To function at your best you have to take on the difficult things, and the hard things are going to hurt. You will want to quit. That is the moment. Not the finish, but the journey. When nobody is watching, stay in it and find out what you are made of. A few commit and keep showing up. That is how you grow.
Hard things are not the punishment. They are the reward. Ask anyone who has won anything. They will tell you about the losses first. Then they will tell you that they kept going.
Consistency. Commitment. Challenge. The pursuit of progress is the art.
Two paths. Take one. Standing still is how you lose.
Nothing sits in a warehouse. Your piece is printed or embroidered after you order it. Give it two to five working days before it ships.
Heavy cotton on the tees, 7.6 oz and 6.1 oz, both garment-dyed. Double piqué on the polo. Four-way stretch knit on the quarter zip.
Buying hands you over to our Printify store to pay. Your card never touches this page. You pick size and colour there.
This site sets no advertising cookies and we do not sell or share anything about you.
The only non-essential thing we collect is anonymous traffic measurement — page views, the site you arrived from, country, and whether you are on a phone or a desktop. No cookies, no profile, nothing that identifies you. It tells us whether anyone is finding the collection.
Essential storage stays on either way — it is what remembers your cart and keeps the site working. If your browser sends a Global Privacy Control signal we switch measurement off for you automatically.
