Absolutely best top I own. Versalite enough to be a baselayer or a solo top that is very warm. Keeps you dry and wicks sweat so fast you can see it bead up or mist off of you. Truly enjoy putting this on every time.
In Japan on a long trip, I wore this to run in and it didn't require washing until after 4 or 5 runs. Very strong moisture management and anti-microbial performance.
