Cold weather warm weather—whatever. Our Merino Sleeveless Tech Layer is going to keep you dry and comfortable over the long haul.

The science behind it is pretty simple. The base layer is comprised of a blend of synthetic hydrophobic VaporRize™ fibers and Merino wool yarns that are naturally hydrophilic meaning that they love pulling moisture away from the skin. And when they do this our blend of fibers distributes it across a large surface area where it can be rapidly evaporated. So when you think about it no moisture buildup means that you won't experience any clammy chills as a result of dramatic temperature swings and your skin jersey and jacket are going to remain dry in order to leave you comfortable.

This material also comes with the added benefit in that Merino actually insulates quite efficiently when it encounters moisture so you'll remain consistently and evenly warm in the winter and cool in the summer—regardless of your level of effort. And with a sleeveless design it opens the door for use with a standard jersey in the summer or arm warmers in the fall or winter.
