belt after the initial tightening is easier for me if I lift the buckle almost perpendicular to my gut then push the belt through to make the final adjustment.

I've worn the belt at work (on my feet all day), while mowing the lawn and on a hike and it hasn't loosened up or needed adjusting. It's light and has a wonderfully thin profile that doesn't make a lump in my untucked polo shirt.

The only thing I'm not crazy about is the squared off end of the belt that goes through the loops. Most all belts are curved on the non buckle end to allow for easier threading through the belt loops. I'll probably cut a curve in mine and melt with a lighter to keep the nylon from fraying.
