W's Torpedo 350


The Torpedo 350 is ideal for those wanting a weather-resistant down bag for sleeping under a tarp or outside in cool conditions. Its low fill-weight makes it a useful all-rounder outside of the mountains, but if you’re happy to push your comfort tolerances, it is suitable for the Alps in summer and for ranges at lower altitudes and/or latitudes. For additional flexibility, it can be upgraded with the addition of a Protium, Deuterium or Tritium sleeping-bag liner from our new Radioactive range (available from June 2016).

The Torpedo 350 is available in Size 1 for women.

Temperature Ratings

EN13537: 5˚C Comfort
-1˚C Lower limit

-10˚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 do 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.

Delivery & Returns

All our products are shipped with UPS for quick, reliable and secure delivery. As most of our products are quite large and/or of high value, they will require a signature. We cannot deliver to P.O. boxes. All orders are dispatched the next working day after receipt (Monday to Friday). Typical delivery time is 2–3 days.

If you change your mind about your purchase, you can return it unused for an exchange or refund, provided it is within 90 days of receipt of your order and the item is still in its original packaging.

Knowledge Base

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.
