Quick answer

Choose the DropTemp Dry Cotton Undershirt for invisible sweat protection under work shirts, or the DropTemp Dry Resort Polo for visible sweat control with resort-ready style and UPF 50+ sun protection.

Sweat protection strategy differs by design

Both tops use DropTemp technology to keep you cool, but they target different sweat zones. The Undershirt places zoned underarm insets to reduce visible sweat stains where they matter most under a dress shirt. The Polo uses a double-knit fabric that moves and dries moisture exceptionally fast across the entire garment, so you stay dry from collar to hem.

Fabric feel and intended use

The Dry Cotton Undershirt feels like a premium cotton tee with stretch, designed to stay tucked and lay flat under clothing. The Dry Resort Polo is a double-knit performance fabric built for standalone wear in warm weather, with a more structured resort look. If you need a base layer, go Undershirt. If you need a shirt that works on its own, go Polo.
