There has never been a blueprint for excellence. Only the chance to try and fail and try again. Here at Groove we strive to reach the top of that hill in everything that we do, testing our ideas over and over until we come up with a product that we couldn't live without. The Groove belt is good for the office, the woods, the backyard and everything in between. Just adjust to fit once and forget. The Groove belt has the perfect amount of stretch giving you the most comfortable all-day fit ever. The buckle uses high strength, neodymium magnets for an easy, seamless snap-on/snap-off. And includes what we like to call Stiff-Tech. Proprietary webbing, rare-earth neodymium magnets and an A380 aluminum alloy buckle, so that when the apocalypse hits and we all move to Mars, you'll be ready for anything. The Groove Belt contains high strength neodymium magnets. Do not wear if you have a pacemaker or any other medical device that may be affected by magnetic fields.
