What Our Gearhead(R) Experts Are Saying:"This is the jacket I rely on for fast, high alpine pushes where every gram matters. The Spectra ripstop is surprisingly tough, and the FUTURELIGHT breathes like a dream even under a pack. It's bomber, breathable, and ultra-packable-basically the holy grail for technical shell layers."For summit pushes in unpredictable weather, we turn to the Summit FUTURELIGHT AMK Jacket from The North Face. Designed with input from elite alpinists and built for maximum performance in extreme conditions, this ultralight shell brings together cutting-edge materials like Spectra(R) ripstop and NANOREFLECT(TM) for a jacket that punches far above its weight class. At under 90 grams per square meter, the 15D FUTURELIGHT fabric is breathable, waterproof, and durable enough for big objectives. Engineered for high-output ascents, the articulated fit allows for full range of motion while climbing, and the bonded-brim hood adjusts easily over a helmet. The laser-perforated draft flap, streamlined chest pocket, and compression stuff sack help minimize bulk without compromising functionality. Lightweight, packable, and designed for performance at altitude, the AMK is a pinnacle shell for mountaineers who demand the absolute best from their gear.
