The Duo-Stack is our training tank — lightweight, built for the days you're moving fast and need a layer that keeps up. Sold as a two-pack, the way you'd stack a supplement: one for today, one for tomorrow.

100% polyester, cut for range of motion, not restriction. No excess fabric, no distractions — just a tank built to disappear into your training and let the work speak.

Available in Pistachio and Blackberry, packaged the way it's meant to be understood — a stack, not a shirt.
