What Our Gearhead(R) Experts Are Saying:"This is the parka I trust for exposed alpine bivvies and summit pushes in full winter. The CLOUD DOWN construction and 1000-fill ProDown keep me warm without bulk, and the Spectra(R) ripstop has held up to rocks and ice tools without issue. It's a serious piece for serious missions."On the coldest missions-when the wind won't quit and the sun never quite makes it above the ridgeline-we rely on the Summit CLOUD DOWN AMK Parka to keep the cold out and our focus sharp. The North Face crafted this expedition-ready layer with innovative CLOUD DOWN baffle construction that eliminates cold spots while keeping weight to a minimum, packing in maximum heat with 1000-fill ProDown(TM) that dries fast and insulates even in variable conditions. The shell combines Spectra(R) ripstop for abrasion resistance with NANOREFLECT(TM) tech that radiates body heat back inward, adding thermal efficiency when every degree matters. A climbing-helmet-compatible hood, internal draft tube, and thumb loop cuffs offer full system coverage for summit pushes and high-alpine belays. From Himalayan peaks to alpine basecamps, this parka is built for our biggest mountain days and coldest nights.
