Outdoor Mummy Sleeping Bag An outdoor mummy sleeping bag is a must-have companion for camping and hiking. Shaped like an envelope, it features a wide shoulder area and uniform width at the foot, offering ample internal space for free movement during sleep without feeling confined. Crafted from high-quality fabric that is waterproof, breathable, and wear-resistant, it shields against outdoor dew, moisture, and scratches from branches. Filled with premium hollow cotton or high-loft down, it delivers excellent warmth retention, keeping you cozy even in low-temperature environments. The top of the sleeping bag is equipped with an adjustable drawstring closure to minimize heat loss, while the two-way zipper design allows easy operation and can even be zipped together with another to form a double sleeping bag. It folds into a compact storage bag for easy carrying, making it an ideal choice for outdoor trips.
