The Montane Dart Men's Long Sleeve Active T-Shirt is the ultimate technical base layer for year-round use during high-intensity mountain pursuits. Whether you are heading out for mountain hiking, trail running, climbing, or multi-day trekking, this shirt delivers superior temperature regulation and reliable moisture management. Made from advanced APEX ECO fabric crafted from 100% recycled polyester with a light fabric weight of just 115 g/m², it offers exceptional next-to-skin softness and unrivaled breathability.

The innovative dual-layer structure of the material ensures that moisture is instantly transferred to the outside, where it evaporates rapidly, keeping your body dry even on the most demanding ascents. The shirt is treated with POLYGIENE® antibacterial technology, which permanently inhibits bacterial growth and prevents unpleasant odors. As a result, it stays fresh even after multiple days of continuous wear, allowing for extended use with less washing—an indispensable feature for long expeditions in the wild.

The shirt boasts a tailored anatomical design in a classic cut (Regular Fit), offering complete freedom of movement without binding. Soft, low-profile flatlock seams prevent chafing and skin irritation under the straps of a heavy backpack. With built-in UPF 20+ sun protection and an impressively light weight of just 155 g (size M), the Montane Dart is a reliable piece of technical apparel for every active mountaineer.
