The Montane Dart Zip men's long-sleeve technical base layer is a versatile garment designed for mountain enthusiasts who demand uncompromising all-season reliability. Crafted from advanced Apex ECO fabric made of 100% recycled polyester, it features an ultra-lightweight fabric weight of 115 g/m². The dual-textured pique knit on the inside wicks moisture away from the skin exceptionally fast to the outside, while maintaining comfortable thermal balance and drying rapidly during high-output activity.

Long-lasting freshness on multi-day mountain excursions is ensured by the integrated POLYGIENE® antibacterial treatment, which uses natural silver salts to effectively prevent odour-causing bacteria, thereby reducing the need for frequent washing. The shirt also offers reliable protection from harmful UV rays with a UPF 20+ rating, a vital asset during long summer ridge traverses or high-altitude climbs.

Constructed with a comfortable standard cut (Regular fit), it features a low-profile collar and a thoughtfully designed 1/4 YKK® front zip. This allows for instant ventilation control during intense ascents, while an integrated internal storm flap prevents uncomfortable chafing against the neck and chin. Strategically placed low-profile flatlock seams (flatlock) and seamless upper shoulders completely eliminate pressure points and chafing under heavy backpack straps.

Weighing a featherlight 160 g, this shirt takes up minimal space in your pack. It is an indispensable piece for hiking, trail running, mountaineering, ski touring, and travel, performing flawlessly as a standalone top in milder conditions or as a dependable technical base layer in colder weather.
