The Montane Alpine Stretch Jacket is designed to be worn on long summer days in the mountains. Wear it on mountain routes either alone, over a baselayer, or as part of a layering system during more hostile weather. Chameleon 3 fabric wicks hard, dries fast & features a four way stretch, so no matter how physical the movement, the Alpine Stretch Jacket will work with you. Fully featured, technically tailored & durably constructed, the Alpine Stretch will give you years of great service.
