Brooks Range Drift 45 Sleeping Bag 45 Degree Down

The Brooks Range Drift 45 Sleeping Bag is an ultralight and compact choice for backpacking at high elevations in the warmer months of the year. Its 850 fill down insulation has the highest warmth to weight ratio available in the Brooks Range collection, so it'll stay surprisingly warm for how little it weighs. Brooks Range treated the insulation with DownTek to retain its lofty warmth when you're exploring damp, wet, and moist environments. Brooks Range treated the Drift's shell with DWR to shed moisture, light rain, and watery spills to keep you comfortably dry all night. The bag uses Brooks Range's unique Flow Construction, which baffles the insulation vertically to reduce shifting and prevent cold spots over time. An internal storage pocket stows electronics that you don't want to get zapped by the cold during the night.
