Brooks-Range Drift 20 Sleeping Bag

Field Notes: This 850-fill Drift 20 made testers salivate in a compression sack the size of a double-meat Subway sandwich. While nearly impossible to restuff, the compressible Drift 20 caught the eye of the fast and light crowd to earn the coveted comment, “If I could afford it, I’d buy it.” 

Pros: Brooks-Range Mountaineering designs are precise and minimal, and the Drift 20 is no different. Aside from a tiny internal pocket, nothing’s added in a bag considered roomy by mountaineering standards. 850-fill DownTek insulation is some of the highest quality insulation on the market. Testers loved the vertical baffles (part of BR’s “Flow Construction”) and puffy draft tube that blocked the cold. Down to 20 degrees, male testers stayed warm in the Drift 20-degree sleeping bag.

Cons: The fabric of this sleeping bag appears susceptible to tear so testers were more careful with the Drift 20 than the Rab Endurance Neutrino 400. 

Favorite Feature: The hood and collar combo feels heavenly on crisp, windy nights as a high-volume baffle surrounds the head like an angel’s halo of warming down clusters.

Tester Comment: “After backpacking with it, I’d take Drift 20 anywhere. Car camping, mid-winter hut trips, bikepacking trips, you name it. It’s a compressible luxury—so comfortable. Once again, if I could afford it, I’d buy it.”

Bottom Line: Though expensive, this compressible bag is a value for serious, do-it-all gram-counters.
