Specifications and Materials

The Finnish M05 sleeping bag from Carinthia boasts impressive specifications. Weighing 2 kg (or 2.6 kg with the compression bag and liner), it's not ultralight, but its durability makes up for it. Dimensions when compressed are 32cm x 25cm. The outer shell is polyamide, claimed to be waterproof (though a bivy bag is recommended for extra protection).

The materials used, including the polyamide outer and inner lining, signify the quality construction. Note that while the outer shell is claimed to be waterproof, it's best practice to use a bivy bag for complete weather protection.
