ACRA 300 g/m² Mummy Sleeping Bag for Cooler Nights, Hiking, and Extended Stays in Nature


The ACRA MUMMY 3 sleeping bag is one of the warmer mummy-style models designed for users seeking greater thermal comfort while camping, fishing, hiking, staying at a campground, or sleeping from spring through fall. Thanks to its mummy cut, the sleeping bag hugs the body more closely, reduces heat loss, and increases sleeping comfort during cooler nights. A major advantage of this model is the combination of higher-density insulation and a cotton inner lining, which feels pleasant against the skin.


The outer fabric is made of 190T polyester, which withstands typical outdoor use well while remaining lightweight. The inner lining features a cotton insert that significantly enhances comfort during extended use and feels more pleasant than standard synthetic inner materials. Thermal comfort is provided by 300 g/m² hollow fiber, which gives the sleeping bag higher insulation than lightweight summer models.


The sleeping bag’s dimensions of 210 × 80/55 cm provide ample space for an adult to sleep comfortably, while the tapered bottom helps retain heat around the feet. The recommended extreme temperature limit is -6 °C, so this model is well-suited for standard three-season use and cooler nights outdoors.


The package also includes a compression sack that reduces the sleeping bag’s volume to about one-third of its original size. When packed, the sleeping bag measures approximately 34 × 20 cm, making it easy to carry in a backpack, car, or among outdoor gear. The total weight of 1.45 kg strikes a good balance between thermal comfort and portability.
