I have many friends who are in the military or who are contracted by the military, and they wear BDUs or ACUs all the time. One thing I have noticed is that they seem to always be comfortable in them.
When I go shoot, I wear what I usually wear: carpenter pants, a t-shirt, and shoes without holes in them... getting gravel in your shoes is no fun.
The only camo item that I own is an ACU-pattern boonie hat. I'll tell you why I like it -- it breathes, keeping the sweat from pouring down my face and neck, it keeps the sun out of my eyes, and keeps my neck from getting sunburned. It's very comfortable.
To be honest, if cammies are as comfortable as they
look, then it's only a matter of time before I try them.
I hafta say, though, I haven't ever seen anybody at the range wearing tight jeans ant a poncho made from a tarp. That's what Rambo looks like, after all.
