Stone Glacier Technical Sleeping Bags

Like backpacks, sleeping bags are an essential piece of gear that every experienced backpack hunter knows not to skimp on. Warmth-to-weight ratios, R-values, temp ratings, packability, and overall weight are a few of the things we calculated to find a solution that will ultimately keep you comfortable and well rested to perform at the highest level on the mountain.

We spent countless hours scouring materials, vendors, testing different designs, and detailing specifications to ultimately create the best-performing sleeping bags we’ve ever used. We partnered with industry-leading material suppliers — Pertex® and Allied Feather and Down — and married them in a cocoon with just the right amount of technical simplicity to produce a sleeping bag worth its weight in gold.
