There are quick release straps on comfort harnesses, but you don't need one. They cost more, and it adds one more thing on your chest that you don't need. If you're hog harness is adjusted properly, you can just "chicken wing" one arm and it will slide right off. It will take an hour or so to set up the webbing the first time on the hog harness, but it's well worth it in my opinion. And don't fear the crotch strap, it makes the whole system stay put.
