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.
