What Our Gearhead(R) Experts Are Saying:"These are the most technical insulated pants I've ever worn. They're incredibly light but ridiculously warm thanks to the 1000-fill ProDown and the unique offset baffle design. Perfect for summit pushes in brutal cold, or long belays when you're not moving much."When we're deep in high alpine terrain and weight savings are everything, the Summit Cloud Down AMK Pant brings expedition-level performance in a barely-there feel. Built by The North Face for elite mountaineers and high-altitude climbers, these pants combine 1000-fill ProDown(TM) insulation with CLOUD DOWN's offset-baffle construction to reduce cold spots and maximize loft without adding bulk. They're light enough for the push to the summit and warm enough for bivvies on the glacier. Crafted from Spectra(R) ripstop with a NANOREFLECT(TM) coating and finished with non-PFC DWR, these pants are as durable as they are weather-resistant. Full-length side zips make for quick transitions over boots or layers, while the elastic waistband and internal fly offer a secure, adjustable fit. They pack down into their own compression sack, making them an essential piece of kit when space and performance are at a premium. Whether we're climbing 8,000 meters or alpine-style objectives closer to home, these pants are built for pushing limits.
