Uniqlo Airism T-Shirt

Uniqlo's Airism t-shirt is a $15 synthetic undershirt that wicks moisture and dries faster than cotton. The fabric is thin enough that it disappears under a button-down without adding any visible bulk. Uniqlo developed the fabric with Toray and the material feels cool against skin even in heat, which is why I wear 1 under everything from August to October. Crew neck sits low enough to hide under a collar and the seams are flat-locked to eliminate ridges. At $15, Uniqlo treats functional basics as engineering projects and prices them so anyone can afford to try them.
