I'm 60+ and not shedding weight like I used to. While this is the most concealable in AZ weather, it was never very comfortable.

I picked up some foam and Velcro and attached it to the bottom body side and its perfect. No digging in even when seated. Not constantly adjusting.

Not sure how durable it will be but give it a try if you're on the fence about appendix carry.

What kind of holster?
Foam?, hehe.

I never thought about that,lol.
