Absolutely the best solution for carrying while wearing gym shorts, joggers or sweats. I have tried a lot of versions of the belly-band, and they all came up short by either not holding the pistol tightly enough to the body or being too bulky. All had an awkward retention/ release system.
The Comfort Concealment belt allows me to use my normal holster with any pants or shorts, facilitating my normal draw from my usual carry position.
It's not quite perfect, but it's the best option on the market.
