Warm, breathable and ready for adventure. Designed for high output mountain pursuits, the new Rolpa Zip Tee features a technical 2-sided brushed anti-pill fleece with strategically placed seams to prevent chafing under your backpack. The quarter-zip function allows you to regulate your temperature with ease - If you're getting too hot, just unzip! (vice versa). The Rolpa has been lovingly handcrafted in Nepal, providing employment, support and wellbeing for the local communities including further funding for vital education and resources. For every product sold, Sherpa makes a generous donation. This is a great midlayer for crisp cold starts in the colder months.
