Well, I listened to David and am currently wearing one of my UA v-necks, ordered from UA directly
I am amazed at how much cooler and more comfortable I am, the sweat doesn't pool up like it used to and if I'm really sweating the shirt stays damp but not heavy like cotton so any breeze is like air conditioning. I'm compleatly sold and now have have enough to get me through a week at a time which is a pretty solid investment in undershirts since I couldn't find v necks for less than $18-20.
I'm now awaiting an archangel, shaggy, and pardus for the G34 so hopefully I will chime in sometime in the next 6 months (hopefully) with some comparisons of those. BTW, is there a support group for holster addiction?
