Warmbac Roll Buckle
Warmbac Roll Buckle belt
Tough, well sewn, made of high quality tape that doesn't roll under load too easily, and the stitching is covered with PVC.
Comes in sensible lengths, the XL size being useful for divers who have to stack lead on a belt. Please specify Standard (c. 34+ inches) or XL (c. 42 inches)
Roll bar buckle. Remember, "there is no such thing as a belay belt" so it's not PPE.
