Our straps are guaranteed for 30 days for defective materials and workmanship. While we cannot guarantee your perspiration and musical activity will not damage the strap, we feel that some road wear and tear just adds to the strap overall viability and look. At some point you will slam your case shut with your strap half hanging out. This may cause a small nick or tear in the leather. We can not guarantee against that. At some point you may roll your amp over your strap and mar the finish. We cannot guarantee against that. At some point you may spin your guitar around your neck creating a heat burn on your skin. We can not guarantee against that.
