I initially didn't know how I wanted to feel about the INVRT but after struggling to find a solution to carrying spare ammo and medical kit with my rifle, I ordered one. I've been dry firing and instructing with the INVRT now for 2 months and love it. it folds up so small and fits in the outside small pouch of my rifle bag and the Rapid Tab helps secure the INVRT to my body securely. If you are looking for something to hold spare mags, 2 rifle and 1 pistol, and a solid med kit, look no further. It goes on quick, stays in place and is there when you need it. I highly recommend these two products together.
