I enjoy it and can wear it with a t-shirt, no issues. I swapped some of the parts around so it is a little deeper and use a little more angle now. I use a bellman belt and it works great. My shirt can be snug and it is still unseen. I also have an LAS Concealment Rampart. It is very comfortable but does not hide as well.
The Zorn is great for AIWB but hurts my hip at 2:30 to 4:00. If you are in to AIWB I would recommend it.
I have a white hat and something else for a larger weapon but, to be honest, the Zorn is so comfortable the other is just too heavy and i have to wear my belt too tight.
A lot of typing, sorry but it works so well.
