When it comes to versatile materials nothing compares to the natural benefits & comfort of Merino wool. Thats why we chose it as the launching pad for the Enduro drirelease Merino 3/4 jersey. Instead youll find that we used our drirelease Merino with Fresh Guard for the construction as it takes the natural moisture wicking antimicrobial characteristics of Merino & enhances them. This means that it will feel even lighter & softer against the skin while also naturally insulating in cool weather keeping you cool & dry in warm weather & ensuring that the stink stays off of you at the same time. Weve also included a zippered side pocket to carry your small items when youre sneaking in a short ride a casual crew neck that helps the jersey play nice with packs & a relaxed fit to keep things flowing & natural while out on the trail. drirelease Merino with Fresh Guard naturally insulates for warmth neutralizes odor & wicks away moisture to keep you dry. One zippered side pocket holds your phone keys or whatever else you need to carry on the trail. Deflect™ UV 30 protects your skin from harmful ultraviolet rays. Relaxed Mountain Bike Fit is the perfect blend of generous & tailored providing a loose comfortable fit for the trail. Fabric Content: 84% Polyester 11% Merino Wool 5% Spandex
