Cotton/Polyester String Underwear
Cool in Summer • Warm in Winter
Engineered for yachtsmen, sportsmen, and outdoor adventurers. Even when wet, the mesh traps air, keeps you comfortable, dries fast, and provides excellent support. Discover the heritage of the Norwegian string vest — now reimagined for modern classic men.
The ingenious origin: Norwegian army innovation
Captain Henrik Natvig Brun – a Norwegian army officer and farmer from Uvdal – invented string mesh underwear in the 1920s. He developed the thermal string vest to keep soldiers and mountain explorers warm and dry in harsh Nordic conditions.
This same principle powers our cotton/polyester string underwear: rapid evaporation, adaptive insulation, and lasting comfort. Trusted by generations of outdoorsmen, now refined with a modern fit for daily performance.
