Don't Sweat It Essentials

Making shirts that don't show sweat means we had to sweat the details.
Sweat Blocking
Fresh Fix Technology® in the underarm panels. That's how not to get sweat stains (and prevent odor too).
Fitted Silhouette
Exceptionally comfortable against your skin, and easily worn under your clothing.
Stretch and Move
We incorporated breathable, 4-way stretch fabrics into the shirt design so you never feel restricted.
