What Our Gearhead(R) Experts Are Saying: "This is my layering MVP for high-output alpine missions. The FUTUREFLEECE fabric is shockingly light but still insulates well, even when I'm sweating on the skintrack. It layers cleanly under a shell, and the pre-tensioned hood fits under my helmet without fuss."We rely on the Summit FUTUREFLEECE AMK Hoodie when every ounce counts and performance is non-negotiable. The North Face's FUTUREFLEECE technology uses a full-loop knit and octa-yarn fibers to create an ultralight layer ideal for technical ascents and alpine layering systems. Built for summit pushes and serious exposure, this hoodie features stretch-woven overlays and NANOREFLECT technology for added durability and thermal efficiency where we need it most. The climbing-helmet-compatible hood, elastic hem and cuffs, and gusseted underarms ensure full mobility without bulk. Designed to function as a next-to-skin layer or a low-profile midlayer under a shell, this piece thrives in demanding conditions where gear must work as hard as we do.
