Like a puffer jacket for your hands: gloves with very light weight surface fabric and top notch insulation. Made for mountaineering and belaying, these gloves are ready to serve us regular folk, too. The idea behind these gloves was inspired by modern day synthetic puffer jackets: why not get insulation for your hands with the same method? The wind is stopped right at the surface, and a high quality technical fiber in the structure keeps air warmed up by your body still, for warmth. Wear as is in dry conditions, or under a pair of waterproof mittens in wet conditions! - Surface: Pertex Quantum Pro Nylon - PrimaLoft Gold insulation, 133g/m² - Faux leather palm patches - Stuff sack included The surface fabric has been solution dyed, to reduce the chemical load and need for water during production.
