The Tree Wool FL T-Shirt is a Hiking Patrol x Mammut collaboration built around a 100% natural fiber blend of Merino wool and biodegradable Lyocell. This combination delivers reliable breathability, fast-drying performance, effective temperature regulation, and natural odor neutralization across a wide range of activities. The relaxed cut is designed to allow freedom of movement without sacrificing a clean, understated look, making it equally at home on the trail, at the crag, or in town. Note: sizing runs large — Mammut recommends selecting one size smaller than usual.
