New for fall 2013, the newest piece in the Simms Waderwick arsenal is the Thermal top and bottom. The Thermal Waderwick top is another great accompaniment for your baselayer system. Throw on Simms’ Waderwick Thermal Top for stacked warmth. Plush, light-wearing Microfiber fleece enhances thermal and wicking properties that beat storms into submission. The anti-pill finish is always smooth. And the ½-Zip easy on-off convenience and self-fabric cuffs of this leading layering piece are equally slick.
