What Our Gearhead(R) Experts Are Saying:"I've relied on the Summit Chamlang Soft Shell Jacket for everything from mixed climbing to spring touring. It blocks wind, sheds light weather, and stretches where it needs to, especially in the back and underarms. It's slim, dialed, and fits under a shell without bulk."Built for rapid ascents and big mountain pushes, the Summit Chamlang Soft Shell Jacket from The North Face combines mobility, durability, and protection into one alpine-ready layer. This lightweight workhorse thrives in high-output pursuits with its slim fit and mapped construction that enhances both performance and comfort on demanding terrain. Constructed with wind-resistant WINDWALL(TM) fabric and four-way stretch, the jacket moves with us while blocking alpine gusts. Targeted lightweight panels under the arms, back, and lower body improve breathability and flexibility without sacrificing warmth or coverage. Seam-taped for low bulk and outfitted with alpine- and harness-compatible pockets, it layers easily under a shell or wears solo when the weather holds. The climbing-helmet-compatible hood, internal hem cinch, and bonded cuffs round out a piece we trust on technical routes and summit missions.
