Built for movement, comfort, and long days outdoors, the Femund PureUll Longs deliver the uncompromising performance of premium merino wool in a clean, versatile design. Whether worn as a next-to-skin base layer for alpine missions or as everyday comfort in colder conditions, these midweight wool longs balance insulation, breathability, and durability with natural ease.

Constructed from Norrona’s exclusive pureUll fabric, this 100% merino wool garment regulates temperature across a wide range of conditions—keeping you warm when it’s cold, cool when activity levels rise, and comfortable even when moisture is present. Ultra-fine 18.5-micron fibers ensure a soft, non-itch feel against the skin, while the single jersey knit with S+Z twisted yarn enhances shape retention and long-term durability.

Designed with flatlock seams and a gusseted crotch, the Femund PureUll Longs move naturally with the body, minimizing chafing and maximizing comfort during extended wear. Naturally odor-resistant and highly breathable, they are ideal for multi-day use, travel, and everyday life—where performance and simplicity matter equally.
