The item I describe as the mine bag is the kahki on that rides towards the bottom. CountyComm has them, they are modeled after the current claymore mine carrying bag.
Ah, oops. I'm not as familiar with TAGs gear, the two pouches are nearly identical externally. The TAG is just a lot thinner.
I was all over the CountyComm site and did not see a bag like this... maybe you are mistaken. <img src="/images/graemlins/confused.gif" alt="" />
BTW: If you are not familiar with the TAG packs/bags how do you know they are a lot thinner?
