Trespass Base Layers

A range of thermal base layers, merino wool base layers and mid layers for all activities including hiking, skiing and running. Base layers work by acting as a second skin and wicking away moisture, such as sweat, to keep you dry and comfortable when getting active in a variety of climes and conditions. Ensure your base layer fits snugly to maximise its body regulating benefits.
