DeFeet International — a Hildebran, N.C.-based manufacturer of socks, gloves, base layers and
related products — recently debuted a line of cycling socks made using Advansa Thermo°Cool™ eco2
high-performance, recycled polyethylene terephthalate fiber from the Netherlands-based polyester
fiber manufacturer Advansa BV.
The fiber features Advansa’s Duoregulation™ technology, which, according to the company,
provides improved evaporative cooling and thermo-buffering performance in a wide range of
temperatures. In addition to the performance provided by the Thermo°Cool fiber, the socks fit
comfortably and are breathable owing to an extra new mesh pattern, and good support thanks to
ergonomically positioned pressure points.
Advansa licensee FilSpec Inc., Canada, is spinning the yarns for DeFeet.
