Smartwool Ultralite Merino Blend Tee [M]

Excellent condition. The Smartwool PhD Ultra Light is unique because it is made of a blend of merino wool and polyester fibers, rather than being made only of polyester like most of the other shirts. It feels drastically different against the skin than the slippery and soft polyester, offering a far more natural feeling. Wool has other advantages as well, such as natural odor control, the ability to manage moisture in liquid or vapor forms, and great durability. The Ultra Light is an excellent choice for running or for other outdoor activities and offers runners an alternative to shirts that are purely synthetic. The Smartwool PhD Ultra Light is made with two different types of fabric: a solidly woven but thin fabric on the front, tops of shoulders, and tops of sleeves, complemented by an airier perforated mesh on the back and undersides of the arms. Both of these fabrics are made of a blend of merino wool and polyester, in a ratio of roughly 56% merino and 44% polyester (although this varies slightly for the main fabric versus the mesh). The advantage of using wool is that it has interesting moisture management properties, is very durable and elastic, and has anti-odor and UPF protection naturally built in.
