All Terrain was started in 1996 when its founder, Todd Hakanson, was hiking in Costa Rica. A bottle of DEET insect repellent he was carrying in his backpack leaked. It ate through his backpack and melted the keys on a calculator he was carrying to figure out exchange rates. Worrying what the DEET was doing to his skin, he began to research the effect of DEET upon his return to the United States. What he found scared him so much that he developed an all-natural insect repellent formula. This formula, Herbal Armor Insect Repellent, is a synergistic blend of five essential oils, which is microencapsulated for release over time. Clinical research at the University of Guelph, in Toronto, indicates that Herbal Armor is 100% effective for over two hours, over 95% for three hours and over 77% effective for four hours.
The company headquarters were moved to Sunapee, NH in 2002. The product line has expanded from its modest clinically tested, DEET-free insect Repellent beginning to now encompass "Natural Remedies for Outdoor Enthusiasts." All Terrain continues to develop, test and introduce quality performance products to help people enjoy the outdoors naturally.
