TRESPASS BASE LAYERS


A base layer is an essential for any efficient layering system, and our collection of base layer sets is ideal for a range of outdoor activities. You'll find everything from hiking base layers and mid layers to merino wool base layers, expertly crafted to wick away moisture in order to keep you dry and comfortable. Ensure your base layer fits snugly to maximise its body regulating benefits.

WALKING BASE LAYERS FOR MAXIMUM COMFORT


There's a reason why hiking base layers are often referred to as a "second skin". They work by absorbing and evaporating your sweat in order to help you stay fresh and comfortable. Our base layer sets are also highly versatile, suited to a variety of outdoor pursuits from hiking to biking. Hit the trails in maximum comfort with one of our walking base layers.
