These are the clothes you'll wear on a day-to-day basis; they'll be the front line, bearing the brunt of rocks, mud, sweat, UV Light and general wear & tear. So they'll have to be tough, and for the situations you'll be in, they'll have to be comfortable. We're talking about wicking breathable, quick-drying fabrics; no-nonsense, insect-repellent, water-repellent, life repellent! (Not literally - they should embrace life, but you know what I mean). Shirts, trousers, all that Jazz. It's here.
