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 the mountains, but it you're happy to push your comfort tolerances, it is suitable for the Alps in late spring/early autumn and for ranges at lower altitudes and/or latitudes.

There is no better insulator than down. Unparalleled in its ability to trap air, incredibly light and highly compressible, down is unbeatable but for one drawback – it must be kept dry. A waterproof down sleeping bag is therefore essential for alpinism.

We use the highest grade of Polish goose down commercially and consistently available. Our sleeping-bag shells are made from eVent fabric – the most breathable and waterproof fabric we know.

Inside the bag, the baffles containing the down are welded to the inner face of the shell, avoiding all stitched seams. For the zip – like stitching, a potential area of water ingress – we use the highly water-resistant Riri Aquazip to ensure that the bag is as waterproof as humanly possible.

|eVent Waterproof Fabrics use Direct Venting Technology - a proprietary and patented waterproof membrane allows millions of tiny pores to breathe at their full potential. Sweat vents directly to the outside of the fabric in one easy step. Click Logo to read more..

Quite a heavyweight for the 0C rating but the real story is the eVent shell, which makes the bag a great choice for altitude but also for tarp camping where a conventional bag could so easily get wet.

The eVent shell is highly breathable so any concerns you may have about being damp in the morning because of a build up of condensation are unfounded. Having used the bag, we have not experienced any problems at all.

Another reason for choosing the Torpedo over other bags could be its durability and hence longevity. The eVent fabric is much more wear resistant than the superlight shell fabrics used on ultralight bags, and the chunky RiRi zipper ensure a Torpedo will go the distance. If you need a tough bag for a long trip, the Crux Torpedo range seems to have been designed with this in mind.

We sell a lot of water resistant sleeping bag covers, if you camp out a lot in the UK under a tarp, then the Torpedo bags could be your Nirvana and you can save the cash you would have spent on a cover!

EN13537:2012 - Look for the 2012 label for the most accurate rating; In 2012 the EN system of testing sleeping bags was re-vamped - the new testing procedures are more rigorous, producing more consistent results than previous tests. 2012 results tend to rate sleeping bags as poorer performing by a few degrees when compared to previous test results, even though the sleeping bag may be identical, or even better.

This means that comparison between an EN13537:2012 rated bag and an EN13537:2002 rated bag are particularly difficult - our advice is to use the new EN13537:2012 rating to compare with other bags who have also been rated in this way.
