Jockey International, Inc.
At Jockey, caring and providing comfort is our responsibility. It drives everything we do. It drives us to listen, innovateand improve. To design thoughtfully. To craft skillfully. To give back wholeheartedly. It's been our motivation since 1876 when our company was founded as a sock company by a retired minister to serve the community. Not because manufacturing socks was a glamorous endeavor, but because Reverend Samuel T. Cooper simply believed the feet of hardworking people deserved better. He vowed to make a difference, and he did. For nearly 150 years, our third-generation, family-owned company is still driven to do things better. Today, Jockeyproducts are sold in more than 140 countries. Our heritage of quality, craftsmanship, and care influences everything we touch — from the fabric of each garment to the lives in communities around the globe. We provide comfort and care because it’s our responsibility. It’s in the fabric of who we are. To experience the quality and craftsmanship, visit Jockey.com.
