I have 3 of them in various colors.. Very simply the best web belt on the market. Far superior to the military's version I wore in the Marines.
If you want to size it yourself, a small hand held propane torch and a sharp knife is the best way..
Heat the knife until glowing with the torch, and it will melt and cut the belt to length.
You can use a piece of masking tape to mark the spot and to make sure you get a square cut if you like. But the weave of the belt makes this simple.
