I find it to be very comfortable, and with the Mustang tucked right up into my armpit, it's well concealed. I don't know yet whether in summer, with just a loose Tshirt, there will be printing or not, so we'll see about that. I also have a Shepherd IWB tuckable for the mustang, which should disappear under a tshirt without a problem. My holster wear ( as my pistol selection) is situational. Out in the woods, walking happily along, I prefer a CZ-75 in a FOBUS paddle holster under a light jacket .
My only doubts about the KangarooCarry rig is how long the pouch will last. Time will tell. For a lightweight pistol, I like the rig.
