My husband is one of those bottomless guys and I'm sick of his pants sliding down the slope! Tried braces but they get in the way + he hates "looking like an old farmer"! (I think he prefers "the old plumber!"). These straps looked like the perfect solution, and for the most part, they work pretty well once you plug them in. The biggest problem I've noticed is that they don't get fixed. on the spot - during the day the setting gradually shifts to the highest, and in the end he seems not to be wearing a belt at all, which definitely defeats the purpose! Type of locking mechanism for adjusting the size.
