These are an amazing alternative to regular suspenders which I found to not be an option for work.  I bought the 2 inch and 1 1/2 inch.  I like the 1 1/2 inch ones more.  They feel very light, and I feel no restriction in mobility.  I like to wear them in conjunction with a loose belt.  It's a relief to not have to tighten my belt to an uncomfortable level in order to have blue jeans stay up properly anymore.

One relative of mine has some mobility problems so he usually wears a type of sweat pants.  He now wears the 1 1/2 inch Hold-Ups as well since a belt is not an option in his situation.  The fact that these attach at the sides is extremely helpful for him since hooking up regular suspenders in the back would always require the assistance of a second person.

The only negative on the 1 1/2 inch version for me is that plastic piece, the ones without the clasp, can slip out of place and go vertical, sort of causing the fabric to bunch up at the narrow ends of the plastic piece.  I didn't have the velcro part perfectly aligned when that occurred, but it still seems like something that could be fixed in an updated design.
