I wear size 34 pants. I bought this medium sized belt which fits me perfectly with a few extra inches left (enough extra length to reach the first belt loop). The webbing is wider than most straps and fits my Tru-Spec pants perfectly (but too wide for many other pants). I don't understand "hidden pocket"; It's so small you can put some coins in it but not a house key. I don't expect to ever use it. The product name says "Safety Friendly" but TSA still makes me take it off at the airport. The band is stiffer than many other woven belts, which seems to make the band lighter. The buckle is simple but more secure than other plastic buckles I've tried.
