Merino wool is extremely breathable and wicks moisture effectively from the skin, making your skin feel dry and fresh. Wool keeps its insulation properties if it gets wet. These qualities makes merino wool underwear an excellent choice of clothing even when doing the most strenuous sports activities. Wool is also naturally antibacterial and odour resistant, so you don't need to wash these pants very often, most times just airing is enough. Note! As opposed to the image, the legs are "4/5" length, meaning the cuffs don't reach your ankles. These properties have, in recent years, made merino wool undergarment a popular choice also among the hikers and trekkers. The Sammal pants (Finnish for moss) are also a good choice for ice fishing. Individual merino wool fibers are significantly smoother than those of regular sheep's wool. Thanks to this, many people who find regular wool itchy can wear merino garments without any problems. - Double insulation layer in the back part, men's fly in
