Sea To Summit Field Repair Buckles are an easy and permanent solution for broken or worn out buckles. The patent pending design allows you to repair broken buckles in the field using only a screwdriver. As an added benefit, there is no need to take it to have replacement buckles sewn on when back from the field. The two-pin side release buckles are a direct replacement for nonadjustable buckles such as those commonly found on dry bag closures and V-pull style waist belts.
