Sierra Designs Base Camp Ye He 40 Degree Sleeping Bag:
New for 2009! The Sierra Designs Base Camp Ye He 40 Degree Sleeping Bag strikes an effective balance between thermal efficiency and roominess. Perfect for warm-weather family camping, the Ye He is available in an array of sizes to accommodate sleepers of varying heights and is insulated with HeatSync synthetic fill. Unlike down fill, the machine washable and fast-drying HeatSync insulation is water-resistant and provides warmth even when wet. This is particularly important if you'll be backpacking or camping in wet climates. A contoured hood with a drawstring cinch ensures a comfortable fit and increase the thermal efficiency of the Ye He 40 Degree bag. An ergonomically-shaped foot box allows for ease of movement while retaining warmth. A fully-insulated draft tube sewn behind the zipper keeps cold air from reaching the inside of the sleeping bag. Dual zippers allow convenient access to the interior of the bag. Integrated pad locks allow for easy attachment to your sleeping pad (sold separately) and help to make sure you stay on your pad throughout the night. An integrated stuff sack sewn into the bottom of the Ye He 40 Degree bag makes it easy to roll-up, store and carry.
