Arctic char have a penchant for brine-y meanderings across some of the most inhospitable climates on the planet. For char in the gnar, or anywhere cold creeps onto the scene, 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.
