Finally a technical base layer top for all you guys out there. The Rena base layer top is produced with the newly developed Hydro-duct technology making the merino wool even more moisture absorbing and water resistant. This means it’ll move sweat and moisture away from the skin keeping you warm and dry. This sporty base layer top is just as good for cold weather training as it is for casual wear. And If you’re looking for something to wear while skiing then look no further.
