The perfect summer travel shirt starts with the right fabric, so the women’s sphere long sleeve Crewe is made from Cool-Lite Icebreaker exclusive blend of Merino wool and Tencel. It stays cooler and breathes better than other fabrics, so this relaxed fitting jersey is comfortable everywhere, from a hot trolley in the city to a long hike on a volcano. With merino’s natural odor resistance, you can wear it more times between washing.
