The Thermowave Merino Flow women's thermal leggings (model 21FLOW752) represent a premium base layer for colder days, designed for ski touring, mountaineering, winter hiking, and running. They are crafted from 100% merino wool, ethically sourced and mulesing-free. Natural fine merino fibers ensure excellent thermoregulation, insulate even when damp, and naturally resist bacterial growth and unpleasant odors, maintaining long-lasting freshness even during multi-day activities.

A key highlight of the Merino Flow model is its advanced 220 g/m² jacquard knit, which creates tiny air pockets within the fabric structure for an exceptional warmth-to-weight ratio, weighing in at only around 200 g. The ergonomic fit hugs the body like a second skin, providing immediate and efficient moisture transport away from the skin to prevent chilling during breaks.

Soft flatlock seams prevent chafing beneath outer layers for flawless comfort, while a gusseted crotch ensures complete freedom of movement on steep ascents. A comfortable elastic waistband keeps the pants securely in place without pinching, and thoughtfully placed side panels complement technical performance by accentuating a flattering feminine silhouette.
