How to make my kydex holster more comfortable?

I have a kydex holster for my edc Glock 43. It’s very comfy and small which I like, but I’m curious on how to make it more comfortable.More often now I’ve been wearing a tee shirt tucked in so that the kydex can rest on it instead of on my skin. But In the summer when it’s hot I hate doing that. And if I just go shirt over my holster the kydex rubs and gets annoying.I have an alien gear holster for my Springfield XD 9, with the foam, but it’s so big and bulky I just want something similar for my kydex or buy one that’s padded somehow. via /r/CCW https://ift.tt/2M7f50Z
