Great for winter and cold weather use Brubeck's Thermo line is made of a two-layered, breathable knitted synthetic fabric. 3D body mapping targets high-sweat areas while keeping other areas warm. With 4-way stretch and charcoal and oxide additives with anti-allergic and bacteriostatic properties are highly technical and comfortable pieces. For some of our staff the Brubeck Thermo tops and bottoms are their favourite go-to base layers.
