Wild Aspen 20 Degree Sleeping Bag vs Therm-a-Rest Boost 650 Sleeping Bag

The Therm-a-Rest Boost 650 is the better bag for most backpackers. It weighs about 2 lb 4 oz versus 4.2 lb for the Wild Aspen, packs smaller, and its 650-fill hydrophobic down and WarmZip shape system give it more usable warmth and versatility. The Wild Aspen is a simple, roomy rectangular synthetic bag that shrugs off damp and suits car campers and budget-focused buyers. Reviewers rate the Boost higher (4.8 from 111 ratings versus 4.6 from 59) and praise its roominess, arm holes and packability, though some note the zipper can catch and a few feathers escape.

• Choose the Wild Aspen 20 if you want a roomy rectangular bag for car camping and damp conditions, and you don't mind the extra weight.
• Choose the Therm-a-Rest Boost 650 if you backpack and want a lighter, more versatile down bag that packs small and adapts from mummy to semi-rectangular.
