What degree sleeping bag for mountaineering? ›

For winter camping and mountaineering (below 20 degrees Fahrenheit), a true winter bag is a necessity. The appropriate temperature rating for cold-weather adventures depends on the conditions, but expedition bags can run all the way down to -40 degrees Fahrenheit or lower.

All the Systems recommended for 8000m use the Hispar 600 sleeping bag. In 'System 1' the bag is combined with the Xero down suit, in 'System 2' the Xero jacket and trousers, and in 'System 3' our revolutionary Double Down Suit. Systems 1 and 2 offer -40°C daytime performance and both are rated for -47°C at night.

Rucksack is a large, rugged bag used by mountaineers to pack all the essentials required for their adventure activity.

Pro-Tip: A 20° bag will get you through most of the year without too much discomfort. For very warm temperatures, it's easy enough to unzip the bag and kick a leg out, and for cold temperatures, wearing extra clothes and using a sleeping bag liner can buy you an extra 10-15 degrees of warmth.

A 0 degree sleeping bag is rated to keep the average sleeper comfortable in environments where temperatures drop to 0°F (-18°C). This rating is crucial for campers and adventurers who plan to brave the colder months or venture into high-altitude locations where temperatures can plummet overnight.

The Altitude™ also features extra down overall and THERMOLITE® panels under the foot area, to help keep heels and ankles warmer. Vertical baffles over the chest section ensure the down insulation cannot migrate or shift to the outside of the bag during sleep, creating cold spots.

The Alpine down mummy sleeping bag is designed for the rarefied world of high-altitude and arctic conditions. It features cutting-edge materials, the highest quality Ultra-Dry down, and complex construction.

If you frequently venture into environments where temperatures drop near or below freezing, a 15-degree bag offers the necessary insulation. Conversely, if your camping trips are mostly in areas with milder nights, a 30-degree bag would provide sufficient warmth without the bulk and weight of a colder-rated bag.

Sleeping Bag Temperature Rating

Campers that plan on using the bag in a variety of conditions should aim for a bag with a temperature rating of +10 degrees to +35 degrees. For those that are camping in cold weather, it's best to look for a bag with a rating between -10 degrees to 10 degrees.

A 40-degree sleeping bag is specifically designed to maintain the sleeper's comfort at temperatures as low as 40°F (around 4°C). This rating signifies the bag's lower limit, suggesting it is most suitable for use in environments where the nighttime temperature doesn't fall below this threshold.

Night time temperatures here hover freezing, but can be much cold, as Kilimanjaro's weather is volatile and unpredictable. We recommend getting a sleeping bag with a temperature rating of 0F/-18C or warmer (-20F/-29C). Someone who sleeps warm can use a bag with a higher temperature rating than someone who sleeps cold.
