Perfect fit for my fiancé. He loves black skin and is slimming, so being able to size with him is perfect. Once tightened, it stays in place and has a unique release button.
Pros
Easy to use. Simply insert the strap into the buckle and pull, the buckle will automatically lock the strap, to release the strap, gently press the lever on the side of the buckle and the latch will engage. Simple, smooth and smooth!
