The Craft ADV SUBZ LS 2 W Women's Functional Long Sleeve T-Shirt can be worn alone or as a base layer under a jacket. It is made of soft and comfortable knitwear that wicks away sweat very well and dries quickly. Mesh panels on the sides and inside the stand ensure better ventilation and even faster sweat drainage. The sleeves are finished with wide cuffs that have a hole for the thumbs.
