The Hammock Underquilt Sleeping Bag Down Blanket Hybrid is the two-in-one sleep system for campers who demand versatility without compromise. Designed to function as both a traditional sleeping bag and a hammock underquilt, this hybrid keeps you warm from every angle — whether you’re suspended between trees or laid out on the ground. The innovative down-cotton hybrid fill — cotton on the bottom for ground insulation, down on top for loft and warmth — delivers balanced comfort across spring, autumn, and winter conditions. At just 980g and a generous 193 × 112 cm open size, it wraps you in warmth without weighing down your pack.
