Trespass Base Layers

Our base layer collection is perfect for all levels of activity, from running and cycling to hillwalking and rambling. 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.
