The opinion of Aventure Nordique

The Alaska 900 from Polish brand Cumulus is a four-season sleeping bag. Lightweight, durable and comfortable, it is ideal for cold and harsh conditions. The comfort temperature is rated at -10° Celsius and it weighs 1,100 grams.

The 900 grams of 700 cuin Polish duck down filling provides cosy warmth. The 37 compartments are V-shaped to prevent cold spots, and the filling is different between the top and bottom. For added protection, the Alaska has an adjustable hood, a removable collar, a fitted mummy shape and protection along the entire length of the zip.

The 35 g/m² Pertex Quantum fabric is durable and water-repellent. It features a full-length YKK zip, inner fabric protection and a self-locking system. The double slider allows you to ventilate at the feet when temperatures rise.

An inside pocket keeps your phone or any small items close at hand and warm. Two loops at the feet allow you to secure or hang (to dry) the Alaska. Comes with two covers: a large one for storage at home and a small one for transport in a rucksack or pulka.

Points to remember

A high-quality sleeping bag to accompany you on your winter adventures, down to -10°C. 700 cuin duck down filling and 35 g/m² Pertex Quantum fabric combine durability and warmth with good compression.
