With a temperature rating of -5 degrees F, the four-season BTU sleeping bag is designed for hard-core snow and alpine enthusiasts, with a variety of warmth-maximizing features. The bag is made using waterproof DriZone fabric, an exceptionally breathable fabric that allows moisture to escape while keeping Mother Nature's moisture out. The performance characteristics give you the opportunity to sleep outside the tent without waking up wet. To keep the interior of the bag clean, you can reverse the bag to expose the Funk!Off antibacterial lining to the sunlight. This helps break down the dirt and oils that accumulate while you sleep, helping the bag feel fresh the next evening. Campers will love the BTU's 800-fill goose-down insulation, which offers an unsurpassed warmth-to-weight ratio.

The bag also includes an Expedition Jacket Hood that's fitted for efficient heat retention, along with an ergonomic, microfleece-lined footbox that gives your feet room to move. Other details include removable pad locks, snag-free zipper tracks, a draft collar, an internal media pocket for your iPhone/MP3 player, a draw cord at the collar, and partial Flex construction on the interior and exterior torso. Available in short, regular, and long sizes, the BTU sleeping bag comes with stuff and storage sacks.
