DaKine Quick Draw Crew Top
Here's what other sites are saying:
If you didn't wear a baselayer under your board jacket it would be pretty uncomfortable under there (chafing, sweat and all). So throw on the Dakine Men's Quick Draw Crew Top to control your under-jacket microclimate. The Quick Draw lives up to it's name and wicks moisture and dries quickly, and it also comes with the Microban antimicrobial treatment so you aren't growing things under there.
