A lightweight summer bag with a solid temerature rating and a great price is found in the Exped Hummingbird 35 Degree Sleeping Bag. Lightweight and highly compressible, the Exped Hummingbird 35 is ideal for spring through autumn trips. Its 750-fill goose down insulation is wrapped in Ultralight Texped nylon and the liner fabric is breathable in the steamiest weather. Side baffles optimize bag warmth by keeping the down evenly distributed. Best of all, as reviewed in Backpacker Magazine, the Hummingbird lives up to its temperature rating. An inner chest pocket doubles as a convenient stuff sack.
