The Montane Dart zip women's long-sleeve technical base layer is an essential all-season piece for a wide range of mountain pursuits. It is crafted from advanced APEX ECO technical fabric with a density of 115 g/m², made entirely from 100% recycled polyester. The dual-layer pique construction provides an optimal balance between comfortable thermal insulation, exceptional breathability, and rapid moisture wicking away from the skin, keeping you dry even during high-intensity output.

For reliable, all-day freshness, the fabric is treated with permanent Polygiene® antibacterial technology, which prevents bacterial growth and odor buildup—invaluable for multi-day treks and expeditions. In addition to premium microclimate control, the top offers UPF 20+ sun protection, making it an excellent choice for both summer ridge traverses and sunny winter ascents.

The top features a well-thought-out design with low-profile flatlock seams that eliminate the risk of chafing when carrying a heavy backpack or layering. A premium front 1/4 YKK zipper with an internal storm flap protects your chin and neck from irritation while allowing quick and efficient ventilation regulation on steep climbs.

With an ultra-lightweight design of just 130 g and a comfortable women's Regular Fit, this shirt is tailored for dynamic outdoor movement. Whether you're trail running, sport climbing, ski touring, or classic hiking, the Montane Dart zip is the perfect technical companion for every adventure.
