Update your bag to bed status.

Your favorite thing about camping just might be the fact that when you're nestled in your Sierra Designs Backcountry Bed 700 Dridown 35 Degree Sleeping Bag, you have trouble distinguishing home from tent. Let's not be rash here, however. Your favorite things about camping are really the red rock landscape and the scent of desert sage brush, but this bag comes in for a close third place. With a unique design that eliminates the zipper, you get an incorporated comforter that acts just like the one on your bed—curl it under, snuggle with it, or toss it off you when it gets warm. Alternatively, should the desert nights cool, you can hook the blanket to the bag sides, cinch the hood around your face, and pretend you were in your traditional mummy bag all along.

Insulated sleeves in the comforter help eliminate drafts, and a sleeve along the bottom lets you slide your sleeping pad in for ultimate roll-around comfort without worrying about that slick rock you set you tent up on. If you're going sans-tent (because the night sky is also a favorite), worry not about dew or morning showers getting your down soggy—this stuff is Dridown, and it stays lofty and retains warmth even when wet.
