Named after a 70's band that used to travel and perform at lean-tos along the Appalachian Trail, the VanGrizzle is seasoned for sure. Actually, we just made that up, but what's pure fact is how a Merino Wool trail sock is at home in the elements – so you don't have to grin and bear them. Performance Fit: No slipping, no bunching, and no blisters. Fine Gauge Knitting: Unprecedented durability and our unique “put it on, forget it’s on” feel. Fast Action Wicking: Pulls moisture away from skin. Fast drying. All Weather Performance: Cool in the summer, warm in the winter. Merino Wool is fast drying, breathable and odor resistant for all-day comfort.
