This bra, made of Merino wool, is great for activities with little to no shock, such as hiking, cross country skiing, cycling and Nordic skating. Merino wool is soft on your skin - the feel is totally different than the one you get from regular, coarse sheep's wool. It also resists odours, and evens out fluctuations in warmth: perfect even for use where you stop for breaks. - Double fabric - 93% wool (Merino), 7% Elastane - Flat lock seams for reduced risk of chafing - Racerback style - The elastic band is covered in soft Merino wool - Naturally odour resistant, great function even when damp Devold undergarments are treated with a natural compound made to protect the apparel from wool-eating insects. It has a gentle, citronella-style scent and is completely harmless to people. The treatment protects the garment for one year and its scent diminishes and fades away with airing the garment. Take good care of your Merino apparel - regular detergents are a bit over the top for use wit
