Baselayers trap a warm layer of air next to the skin whilst wicking moisture away into the next layer of clothing. Wicking occurs due to the warmth of the body driving heat and moisture from a warm surface (high pressure) to the colder outer layers (low pressure). At Somerset Camping you'll find a large range of mens baselayer tops and leggings for all weathers. NOTE: The sweat we produce when we exercise travels through the layers to evaporate on the surface of the outer layer. Therefore there will be dampness within the layers – a good Baselayer will keep this dampness off the skin – so you are a bit damp. BUT. you feel dry.
