Torpedo 700
£799 / €899 / $ 1095

This is the bag for the active mountaineer climbing winter alpine routes and/or peaks of 6000–7000 metres in South America and the Greater Ranges. The Torpedo's waterproof shell means that you can bivouac outside or in a single-skin shelter without ever having to worry about your down becoming damp. In line with our policy that ruggedness and durability come first, the shell fabric is also considerably more robust than the lightweight fabrics in common usage. Plus it also has a quiet handle (for rustle-free sleep).

Like the 500 and 900, the Torpedo 700 is available in three lengths and two widths. Look at our sleeping bag selection chart for guidelines.

For additional flexibility, the Torpedo 700 can be upgraded by combining it with a Protium, Deuterium or Tritium sleeping-bag liner from our Radioactive range.

Temperature Ratings

EN13537: -4˚C Comfort
-10˚C Lower limit
-28˚C Extreme

The comfort rating represents the lowest temperature at which a standard adult FEMALE can have a comfortable night’s sleep.

The lower limit represents the lowest temperature at which a standard adult MALE is deemed able to have a comfortable night’s sleep.

We like the EN13537 ratings at crux. Going by our own extensive experience, we feel they accurately reflect the temperature limitations of each sleeping bag for a comfortable night’s sleep. Individual tolerances may allow some people to go beyond these figures, but we believe this is at the discretion of the user and is not something to be claimed by us.

Care & Attention

Down is a very resilient insulating material and with basic care, any down sleeping bag should last you a very long time (if not your entire active climbing life).

There are two simple rules to ensure longevity:
1. Always store your sleeping bag uncompressed in a dry, airy place
2. Always use a sleeping bag liner. This will prevent the bulk of body oils and perspiration from getting into the down itself and reduce the need for washing the bag.

NEVER machine-wash an eVent-shelled down sleeping bag. We highly recommend you hand-wash your down sleeping bag or, alternatively, use a professional service. You can download washing instructions here.

Knowledge Base

Crux sleeping bags, just like our rucksacks and tents, are wholly a product of their specification. The key criteria – in this case, warmth and weight – are completely dependent upon the quality of the goose down (the only kind of insulation you will find in crux bags), the fabrics and the components employed. For the customer in the shop, however, facing a colourful selection of sleeping bags that all look much alike, how can you tell which one will keep you warm when it really matters? Even obvious yardsticks such as the thinness or thickness of a bag can be misleading. In this Knowledge Base you should find all the technical information (including some demystifications) you need in order to understand what makes a good bag – and what makes crux bags the best.
