"Bend but don't break" with our newest addition to our line of socks. As always we blend the highest quality yarns to produce a sock that is smooth and offers absolute comfort while at the same time being resilient and very long wearing. Like our other bamboo cellulose based viscose socks, these are super absorbent, moisture-wicking, breathable, and will not harbor odor like other synthetic based socks. 87% Viscose from Bamboo, 10% Nylon and 3% Spandex. Designed in California, made in China.
