It’s a base layer. It’s a top layer. Wait, it’s both. The all new MeCo 250 Long Sleeve Zip Tee by UK-based Rab is made from an innovative merino wool blend with recycled polyester, producing a fabric that offers all the benefits of merino wool (breath-ability, anti-odor) except that it dries up to 5 times faster. It also has thumb loops to keep your hands warm, a great stand-up collar and a slim fit. In fact, it’s so stylish, that you’ll probably forget that it was designed to be a base layer, so you’ll want to wear it for all sorts of activities and even around town too. Comes in Dragonfruit and Ebony.
