Blue Flame E-Tech Bamboo Thermal Socks

Size *
Color None Selected

Current stock: 0







We took the thermal properties of the original blue flame and blended it with the super moisture wicking and evaporative properties of bamboo viscose to keep your feet drier.  A dry foot is easier to keep insulated but evne so this sock is constructed with thick loops of cushioning that help trap heat in.  This sock rates 4 flames out of 4 for thermal properties.
