Many climbers and alpinists cant travel with a full-length, cumbersome, sleeping bag. Eliminating the need to carry a bulky bag, The North Face Elephants Foot sleeping bag is a lightweight sleep system that provides the ultimate lightweight, packable solution. Made from our awesome HyVent DT fabric and Climashield Neo insulation, this waterproof, breathable fabric is durable and extremely compressible. Combined with a down or synthetic parka at night, the Elephants Foot keeps explorers warm while lodging vertical for the night en route to the summit.
Great bag
Almost perfect for my uses (alpine bivis and bicycle touring). Just one drawback... the reinforced patch in the foot area (designed so that you can wear you mountain boots inside the bag) also causes a fair bit of condensation in the foot area... even with the my approach shoes on, I found my feet quite damp most mornings. It's kind of like a vapor barrier effect, keeps your feet warm but also a bit damp... not really a huge problem, but after 4 days, I got tired of damp socks. Also, if you are 6'6" like I am, the bag only pulls up to just above the waist... whereas, my wife can pull it up just under her arms (she's 5'8"). This is no big deal if you have a longer puffy jacket... the bag also kept us both warm down to the low 30's... but you do need a good puffy jacket to keep the upper body warm.
