Our Merino Long Johns are at their best when conditions or activity require moisture to be removed from the skin, or when temperatures and activity levels vary. Thanks to nature and our technical solutions, our Merino Long Johns remove moisture while cooling in the heat and warming in the cold. The Merino Long Johns can be used as a base or intermediate layer with the Svala Thermal Collection on top. Breathable long johns for layering at work and leisure. The fabric has a technical two-layer structure with an inner layer of moisture-wicking polypropylene and an outer layer of heat-binding SuperWash and anti-moth treated Merino wool. All seams are flat sewn, so the product is comfortable to wear with no pressure or rubbing. There is a fly at front. Machine wash at 40°, preferably with wool detergent. Materials: 75% Merino wool, 22% polypropylene, 3% polyamide
