I suffer from noarseatall and it was indeed a blessing to be able to "fit in perfectly" where it would hold my pants. Anything heavier than the fluff in my backpack pocket succumbs to gravity, so a belt is a must for everything but gym pants. Unfortunately, I'd have to choose between a slightly uncomfortable or slightly loose traditional belt because I've always ended up between the notches. Not anymore, now everything is perfect. Depending on what I'm doing, it can take a few hours to get back into a perfect fit, but that's nothing compared to constantly having to pull my pants up because I've decided to go a little looser to avoid tummy discomfort . Highly recommend for anyone suffering from Noarseall to avoid unwanted tears.
