When it comes to versatile materials, nothing compares to the natural benefits and comfort of Merino wool. That's why we chose it as the launching pad for the Men's Enduro drirelease® Merino 3/4 Jersey from Specialized.Instead, you'll find that we used our drirelease® Merino with FreshGuard for the construction, as it takes the natural moisture wicking, antimicrobial characteristics of Merino and enhances them. This means that it will feel even lighter and softer against the skin, while also naturally insulating in cool weather, keeping you cool and dry in warm weather, and ensuring that the stink stays off of you at the same time.We've also included a zippered side pocket to carry your small items when you're sneaking in a short ride, a casual crew neck that helps the jersey play nice with packs, and a relaxed fit to keep things flowing and natural while out on the trail.
