Intrepid Explorers are a group of people dedicated to the pursuit of all things outdoors. They are extremely self-reliant, and as such don't want equipment that fails. They have taken some of our standard designs and "beefed" them up in such a way that insures a long, reliable strap life. You can order their designs right here.
