In the mountains, the deserts, the forests, and even our driveways, we’ve been slumbering away in sleeping bags now for months. We’ve tried mummies, down bags, synthetic bags, thin, thick, wide, and tapered. We don’t normally recommend synthetic bags in the backcountry, but we’d be confident sending friends out in one of these.

When on a budget, always go used when it comes to important backpacking gear.
