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. Because of its waterproof shell, you can bivouac out in the open or use single-skin shelters without ever having to worry about your down becoming damp. The shell fabric not only has a quiet handle (for rustle-free sleep), but it is considerably more robust than the lightweight fabrics commonly used. Our policy is that ruggedness and durability come first. Look at our sleeping bag selection chart for guidelines.
The Torpedo 700 can be upgraded with the addition of one of new Radioactive range of sleeping bag liners (which can also be used as stand-alone ultralight bags) which will be available from Spring 2016.

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. Try to keep it as clean as possible to minimize washing (this ultimately damages the down).
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.
In a shop, sleeping bags appear to be one of the easiest products to buy. Whilst they come in a variety of colours and fabrics, and obviously range from thick to thin depending on how warm you want to be, their design and shape tell you little. The insulation – and at crux we only talk about down – is the part that does the job of keeping you warm, and this is virtually impossible to assess by touching or looking at it. Additionally, from a design point of view sleeping bags offer very little room for creativity (even cosmetically) and hence, more than anything else we manufacture, sleeping bags are very much a product of their specification. The key criteria – warmth and weight – are completely dependent upon the insulation, fabrics and components used. Consequently, our knowledge base has a more extensive range of subjects and information than any other group of products.
