The North Face Elephant's Foot Sleeping Bag

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.
