The Montane Women's Malli Long Sleeve Merino T-Shirt is a premium women's long-sleeve technical base layer engineered for demanding alpine pursuits, mountaineering, climbing, trekking, and ski touring in all seasons. Weighing in at an exceptionally light 145 g, it delivers the perfect balance of featherweight comfort and reliable thermal protection. This piece serves as an essential base layer that performs brilliantly when worn on its own in cool conditions or as a dependable foundation beneath a technical windshell or insulated jacket.

The standout feature of this shirt is its advanced Core Spun Merino technology, where a durable nylon core is precisely wrapped in ultra-fine, 18.5-micron merino wool. A sophisticated technical blend of 84% merino wool, 11% polyamide (nylon), and 5% elastane with a fabric weight of 140 g/m² unites the best properties of natural and synthetic fibers. Natural merino wool provides outstanding thermoregulation, breathability, and natural odor resistance during multi-day tours, while the nylon core ensures superior abrasion resistance and elastane delivers stretch and shape retention.

An ergonomic Trim fit combined with four-way stretch allows unhindered freedom of movement while tailoring closely to the female form. Low-profile flat merrow seams and soft-touch cuffs eliminate chafing and pressure points under heavy backpack straps for long-lasting comfort. Featuring reliable natural sun protection of UPF 30 and certified to the Responsible Wool Standard (RWS), this shirt is an indispensable choice for every outdoor enthusiast.
