Every man who trains owns two wardrobes: the clothes he works out in, and the clothes he's willing to be seen in. Rockwell exists to collapse that into one.

The vest is 220 GSM ribbed cotton with 5% elastane — enough stretch to move through a full range. This one has enough body to stay opaque and enough elastane to move with a full overhead press without riding up.

The ribbed knit does the aesthetic work. It holds a straight line down the torso instead of clinging, which is the difference between a vest that flatters a trained frame and one that shrink-wraps it. Armholes cut close enough to stay put through a set, not so wide that they only work in a gym.

Breathable cotton, so it wears comfortably through a full session and doesn't hold heat on the walk home. Five colours — Black, White, Brown, Olive, Grey — so wearing it four times a week doesn't look like wearing it four times a week.

Train in it. Then don't bother changing.
