Ultralight backpacking trips and summer campsites call for Exped's Dreamwalker Syn 133 Sleeping Bag. When summer mornings still feel brisk, you can convert this sleeping bag into a parka with zippered armholes and a drawcord adjustable footbox. That means you can get up and make the campfire and breakfast without a shiver. At night, the Dreamwalker ensures warmth through most summer nights. Its synthetic insulation stays warm in wet environments, and it'll quickly dry any water spills so you don't freeze at night. The full length center zipper lets you wear this bag like a blanket for warmer summer evenings.
