Typhoon Duotherm and Monotherm Undersuits

The Typhoon Duotherm Undersuit is designed for surface use in extreme conditions.

This undersuit is made from a double layer of 100-g fleece, which gives it very high stretchability as well as extreme breathablity and minimal weight.

The TOG rating of 3.5 makes it ideal for those winter days.

Also available is the Typhoon Monotherm Undersuit, a single-skin monotherm version with a TOG rating of 2.

Please note: Typhoon unisex suits are based on the men's size chart.
