The Montane Deep Heat minus 20°C Sleeping Bag enables you to sleep in warmth and comfort through even the harshest mountain-top conditions because Montane have transferred their expertise in technical extreme cold-weather materials and construction from their high-altitude clothing range.

The design details for this top-quality sleeping bag reflect how people actually sleep, where they need protection from the cold through space management with closer or looser fitting elements adjustable to suit the individual needs.

The design of the Montane Deep Heat minus 20°C Sleeping Bag is full of practical details with the head, face, neck, shoulders, lower legs and feet all given specific design detailing to enhance the overnight comfort, warmth and convenience of this sophisticated sleeping bag.

The high-quality, high fill-power goose down will keep you warm but also comfortable thanks to the softness of the PEAQ Down liner against your skin. The YKK Vislon zip is positioned to avoid contact with you and also to be easy to operate through the night. And the shaping of the bag and the positioning of its vertical baffles contribute to the elimination of cold spots.

For daytime, there are such conveniences as a zip that opens the bag right out for quicker drying, loops for hanging out the bag for airing and a dry bag that doubles as a pillow if stuffed with clothing and that is specifically shaped to fit into a backpack base compartment.
