With a 500g fill-weight, the Torpedo 500 is a classic Alpine mountaineering bag. Suitable for most summer mountaineering in ranges up to 5000 metres, the 500 can also be pushed into the shoulder periods of spring and autumn at lower altitudes. It is equally a very useful bag for non-mountaineering activities such as back-country hiking, trekking or travelling. With its weather-resistant shell and premium down fill, the Torpedo 500 is the most versatile bag in the crux range.
Like the 700 and 900, the Torpedo 500 is available in three lengths and two widths. Look at our sleeping bag selection chart for guidelines.
For additional flexibility, the Torpedo 500 can be upgraded by combining it with a Protium, Deuterium or Tritium sleeping-bag liner from our new Radioactive range (available from June 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. 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.

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.
