The Arma-S suit comprises technology new to Rukka for 2010. The Arma-S uses Superfabric technology on the shoulders, elbows and knees. This exciting new technology makes any surface covered with Superfabric be puncture resistant, cut resistant, abrasion resistant, flame resistant and yet still enables these areas to be flexible and breathable. Rukka have also done away with the traditional zip for the jacket, favouring the new fully waterproof Gore-Tex Lockout closure system instead.
