New for fall 2013, the newest piece in the Simms Waderwick arsenal is the Core crew top and bottom. This Corel Waderwick top from Simms is another great accompaniment for your baselayer system. The crew top features Simms’ new Baselayerfit for body-contouring warmth and comfort. Two-way stretch knit fabric combines massive breathability with flexibility that favors a full range of motion, while raglan sleeves ramp up overall comfort.
