The Onewind Down Underquilt is a great choice for camping in the desert, a thru-hike in the woods, or a blitz around the mountain trail in winter. This is designed to keep you snug and cozy even when it's freezing. It has an adaptable suspension system that can be used with almost any hammock. Easy-to-reach shock cords give you unparalleled temperature control for warmer or colder nights.
