EASY TO CARRY - ZTTENLLY sleeping bags are filled with 33.5 oz of premium duck down and weigh only 3.4 lb for the regular and 3.9 lb for the long models, achieving a minimum compression volume of 11.4 x 7.4 x 7.4in. Ultra-lightweight and ultra-small footprint make your outdoor activities much easier. WARM AS A QUILT - 550FP and 600FP down fill make it like sleeping under a comforter. For a warmer night's sleep, we block any place where cold air can enter and heat can be lost. zipper draft tubes, 20D water-repellent shells, and a U-shaped neck collar all reduce heat loss. MORE USER-FRIENDLY DESIGN - With its anti-clip design and two-way zipper, it is easy to get into and out of. The sleeping bag can also serve as a sleeping mat and quilt, or the soles of your feet can be opened separately to let air in. FREEDOM AND WARMTH AT ONCE - Due to its semi-rectangular shape, you do not find it as difficult to flip as the mummy style, nor does it lose heat as the envelope style due to its oversized space.
