Tough kids deserve a tough sock. So we put the same great construction from our Hiking Socks directly into our kids'. Built to withstand the worst conditions the great outdoors can dish out but still be ultra comfy. Happy feet = Happy campers. True Seamless construction provides a smooth, performance fit to assure there's no slipping, no bunching, and no blisters. With half the wool yarn weight of our cushion socks, our lightweight cushion socks deliver lightweight performance with the perfect amount of cushioning along the base of your foot, while 17.2 Micron Merino Wool deliver supreme comfort. Breathable and fast drying. This "all-weather" sock stays cool in the summer and warm in the winter, plus it's naturally antimicrobial so it repels bacteria and odor'a great feature when you need to get an extra day (or two) out of your socks. Still made in Vermont. Guaranteed for life.
