Extremely durable and breathable synthetic insulated lightweight hooded jacket for high intensity activities. The Proton hooded jacket is equipped with breathable insulation that adapts to varying needs in mountain sports and acts as a self-regulating intermediate layer in many different types of intensive activities. Breathable insulation means that excess heat and moisture escapes through the combination of air-permeable fabric and insulation. As well as being extremely breathable, the outer fabric Fortius™ Air 20 has superior abrasion resistance. It withstands over 60 times more than the industry standard in wear tests. The Coreloft™ Compact 80 synthetic insulation in the main body has excellent ability to recover its shape after being stretched. The No Slip Zip™ system ensures that the main zip does not open by itself, and the helmet-compatible insulated hood provides extra warmth. Put it on, wear it and focus on what you're doing.
