These belts are better suited for guys without a gut. I sit at a desk all day with my dad bod and, while it is more comfortable than some other belts, the buckle will poke into my gut. The belt keeps the tightness well but I find myself loosening it if I have to sit down for a long period of time and then tightening it again if I am in an upright position. The undoing of the belt takes more time than a traditional belt. So give yourself an additional 5 seconds to drop off the kids at the pool. Overall, it is a good belt. It does the job. It is a little pricey for what you get. I wish that they would come out with a flexible belt option to give it more support when going from a seated to upright position.
