REVELATION APEX SYNTHETIC FILL|Our original and best-selling sleeping quilt, but with APEX Synthetic fill! A favorite of long-distance hikers, the Revelation Sleeping Quilt is known for its amazing versatility, thoughtful design, and ultralight weight. On warm nights, the Revelation can lay open as a blanket, and in colder temperatures, you can cinch the adjustable 1/4 length zipper footbox closed. This design allows you to dial in a comfortable night’s sleep in a wide range of different temperatures and climates. The perfect option for active sleepers! The Revelation is a sleeping quilt, not a sleeping bag, which means it’s designed to be used with a sleeping pad to provide insulation underneath you, between you and the ground. The Revelation doesn’t have a full-length zipper or a built-in hood, saving weight and space in your pack.|FILL & FABRIC|CLIMASHIELD™ APEX insulation performs better than down in wet and humid conditions, dries quickly, packs small, and is easy to clean. CLIMASHIELD™ APEX weights may vary +/- 10% due to production variances. Read more about EE Fills on their site. Ultralight nylon fabric.
