When it comes to high-output adventures like touring the backcountry or hiking to a new climbing spot, the La Sportiva Ascent Primaloft Jacket is a vital part of our winter activities. It features a lightweight, warm construction with the combination of Primaloft Silver Eco insulation and Vapovent technology, while the stretch fabric on the sides and sleeves provides optimal freedom of movement. There is also a wide variety of pocket space with a zippered chest pocket, two invisible zipper pockets, and an added storage pocket to keep our gear safe and secure.
