Technical Clothing

The word technical is much overused in the outdoor trade where it is applied to just about everything sold in a bid to make it seem more glamorous. In using it for this section, we apologise, but it does sum up simply the notion of clothing designed to deal with extreme mountain weather.

A "traditional" technical clothing system consists of a Base Layer of quick wicking "thermal" underwear, one or more Mid Layers - usually but not always fleece, and a Shell Layer - usually but not always waterproof.

The idea is that one varies the mid layer and may do away altogether with it and part of the base layer dependent on conditions, and in principal this system applies to just about all mountaineering situations, though there are various flies in the ointment.
