Eliminate the need to stop and change layers as you close in on the summit, with this highly breathable and adaptable synthetic insulated jacket. It combines PrimaLoft Gold Active insulation, which breathes and insulates through peaks and troughs of activity, with low-bulk Thermic stretch fleece side panels that offer superb mobility and make the jacket easy to layer. The breathable yet wind-resistant Pertex Quantum Air fabric deflects windchill while responding to your output, keeping you comfortable on tough ascents in mixed conditions. The result is lightweight, packable active insulation you can wear as a warm layer or technical outer, from the dawn start to the summit push.
