Merino wool is highly comfortable to wear, and especially practical in long outdoor excursions as it needs to be washed much less frequently than synthetic base layer materials. It also feels comfortable on your skin even when moist. Individual merino wool fibers are significantly smoother than regular sheeps wool. Thanks to this, many people who find wool itchy can wear merino garments without any issue - Other parts made of a Merino wool blend - this material is in contact with you even at the wind protected area - Material weight 160g/m² - Flat lock seams - Machine washable: do not use bleach or fabric softeners; ideally wash with wool detergent and on a wool cycle Note! A similar model has previously been sold with a windproof panel. *This product does not offer wind protection*, these are regular Merino boxers.
