The Montane Dart is an exceptionally versatile women's long-sleeve technical baselayer, designed as an essential first layer for year-round mountain use and dynamic outdoor sports. Whether you're heading out for a fast mountain run, a multi-day trek, or a climbing adventure, this shirt provides excellent thermal balance and next-to-skin comfort.

Made from lightweight technical APEX ECO fabric, consisting of 100% recycled polyester with a weight of 115 g/m². The dual-layer pique fabric structure wicks moisture away from the skin rapidly and dries extremely fast, keeping you comfortably dry even during intense exertion. For carefree sunny ascents in alpine terrain, the material also offers reliable UV protection with a UPF 20+ rating.

Long-lasting freshness on multi-day adventures is ensured by Polygiene® antibacterial treatment, which effectively prevents bacterial growth and odor buildup. A tailored fit, low-profile flatlock seams that prevent chafing under backpack straps, and an ultralight weight of just 120 g make this a top you'll happily wear on its own or as a dependable foundation in your layering system.
