Icebreaker Anatomica S/S Crewe Merino base layer Men (XL, black) - The Anatomica S/S Crewe from Icebreaker features a blend of merino wool and synthetic fibre. This makes the functional shirt comfortable, even in warm temperatures and during strenuous activities. The material combination improves the drying properties of the merino wool, but the T-shirt will also retain its natural functional properties. The merino base layer is temperature-regulating, breathable, and doesn't absorb unpleasant odours. Icebreaker gave this T-shirt a nice form-fitting cut. All of its seams are flat, and the elastic component gives it the necessary stretch. The Anatomica S/S Crewe from Icebreaker is a highly-functional base layer for the entire year!
