This is the belt I have been wanting for a few years!
Very sturdy, waterproof, and best of all, it doesn't slip!  I tried very hard to make it slip when it was tight around my waist, but it wouldn't slip.
I bought a similar belt from Cabela's recently, but found that it doesn't hold tight, so I took it back--and it was $7 more expensive than JASGOOD.
I am also happy with the extra buckle, because there is always the worry of breakage.  Replacing the buckle and adjusting the length of this belt are very easy to do.
