The Rossignol W Ruby Impr M has Primaloft Silver insulation, which retains body heat, and an Imp'R membrane, which offers excellent waterproofing while being breathable. This effectively drains moisture away from the body for faster drying. The Micro Bemberg inner lining provides good additional thermal insulation, and the soft goat leather ensures a good grip, and a more reliable hold on the pole.
