What Our Gearhead® Experts Are Saying:"I’ve used this version of the Greystone on cold nights in the Sierras and stayed warm without overheating. The DownTek fill insulates really well even in damp conditions, and I appreciate the contoured shape—it helps seal in warmth efficiently without adding weight or bulk."When cold weather rolls in, we turn to the Greystone 20 600 DownTek Sleeping Bag for dependable warmth and comfort deep in the backcountry. Built with 650-fill DownTek™ insulation and a water-repellent recycled shell, this bag delivers cozy performance whether we’re tucked into a tent at tree line or sleeping out beneath the stars. The thoughtful design and reliable warmth make it a go-to for three-season adventures.Its DownTek™ insulation stays lofty and warm even when exposed to moisture, while the contoured hood, insulated draft collar, and no-draft zipper system seal in precious body heat. The water-repellent shell and lining are made without intentionally added PFAS, so we rest easier knowing our gear is more eco-conscious. And with a pack size of just 9 x 20 inches and a trail weight under 2lb 11oz, the Greystone fits easily into our overnight kit without weighing us down.
