Trekking Base Layers

Our collection of trekking base layers ranges from simple, affordable vests and fleece-lined trousers to seamless performance tops that mould to the contours of your body. Most of our styles are made from wool which is renowned for its warming yet breathable properties, and because it’s naturally antibacterial and great at controlling odours – hiking is sweaty work!

Trekking Base Layers

Discover our collection of trekking base layers, the unsung heroes of your outdoor wardrobe. Ranging from simple vests and fleece lined trousers to seamless performance tops, alongside your trekking socks these versatile layers are the first defence against the elements. Made from breathable materials, base layers are designed to keep you dry and regulate your body temperature, no matter the weather conditions. Worn under trekking jackets and trousers, they provide insulation without bulk, making them perfect for layering on winter treks with a trekking fleece mid layer or wearing as a moisture-wicking and anti-chafing layer on summer trails.
