Comparative test of the thermal insulation of down jackets

  Two down jackets were tested: one from the K-Way brand and one from the Penfield brand (sleeveless) Two types of tests were carried out: using a heating film placed inside the down jackets; by measuring the losses through the down jackets when they are worn by a person. In both cases, the objective is […] [Lire la suite]
