Here is the 3/4 crew sock everyone is talking about. Beware of imitations! These socks, like the rest of Spun Bamboo brand products, are the highest quality we can make. We use only the best 133 needle knitting machines to make a superbly constructed sock that is like silk on your feet. Cushion and support where you want it, this sock is truly performance driven. Like our other socks, our crew is super absorbent, moisture-wicking, breathable, and will not harbor odor like synthetic based socks. 87% Viscose from Bamboo, 10% Nylon and 3% Spandex.
