Mammut Tree Wool FL Longsleeve Men Shirt

Lightweight men's merino long‑sleeve first layer. The fabric blends 50% Merino wool with 50% Lyocell (Tencel™) to provide thermal comfort, natural odour control and a soft next‑to‑skin feel.

Main benefits

• Natural thermal regulation: merino retains warmth even when damp.
• Faster drying: Lyocell/Tencel™ mix wicks moisture faster than traditional wool fabrics.
• Odour control: merino reduces bacterial odours during extended wear.
• Freedom of movement: underarm gussets improve mobility for climbing and scrambling.
• Versatile fit: regular fit layers easily under shells and insulated jackets.

Designed as a base layer for mountaineering, climbing, hiking, ski touring, via ferrata and travel in cool to cold conditions where a combination of warmth, comfort and moisture management is required.
