Big Agnes packed a lot of warmth into its Pomer Hoit UL 0 Degree Down Sleeping Bag. A member of Big Agnes' highly technical Divide Superlight series, the Pomer Hoit has been updated with the addition of hydrophobic down insulation as well as a water resistant treatment to its outer fabric. Big Agnes also employed its innovative top only design, so all that fluffy warmth is on top where it can actually do some good underneath, you'll find a sleeve, into which you can slip your sleeping pad for effective insulation against the cold, hard ground. The no draft zipper tube, collar, and wedge between the bag and pad virtually eliminates areas of cold air leaks, so you keep that warmth you're generating all to yourself. Stuff your sleeping pad into the half length sleeve, attach your liner to the interior loops if you feel the need, stick your camp pillow into the pillow pocket, and rest easy during the storm.
