The CCM Proline Level 5 Cut Resistant Hockey Socks have been specifically designed to give players great resistance to cut-type impacts. This is thanks to the Dyneema fiber, the world’s strongest fiber, that the socks are constructed out of. This fiber is lightweight, breathable, and cut-resistant, all while remaining incredibly comfortable! The double welted CCM cuff at the top of the CCM Cut Resistant Hockey Socks helps keep the sock tightly, but comfortably, in place on the leg. Keep yourself well protected with the CCM Proline Level 5 Cut Resistant Hockey Socks! 40% Dyneema, 30% nylon, 15% glass, 10% polyester, 5% spandex
