The Big Agnes Sunbeam Sleeping Bag: 30 Degree Synthetic helps you sleep comfortably on your weekend camping and backpacking trips. It is designed to keep you warm through wet conditions due to its water resistant face fabric and synthetic insulation that retains its loft when wet. Additionally, the Sunbeam is designed to stretch to accommodate your 20 to 25 inch sleeping pad to keep your sleeping kit secure throughout the night for added warmth. The bag is designed to keep you comfortable down to 30 degrees Fahrenheit but thanks to the interior fabric loops you can attach a sleeping bag liner if you plan on being in slightly cooler temperatures. Aside from warmth, the Sunbeam has additional features for comfort and convenience. To begin with, it has an anti-snag zipper for a smooth and quick zip. A Free Range Hood and foot box allow you to lift your head and wiggle your feet respectively. Additionally, a pillow barn secures your pill through the night even when you're tossing and turning and an internal hood drawcord provides you with a secure and comfortable fit when it is cinched. Finally, when it's time to move on to a different camp, the whole bag compresses down small into its stuff sack for convenient transport.
