I reckon after working in it all day, packing mags in it just doesn't seem to be a problem to me. Don't get me wrong, sweat in the eye is sweat in the eye. I guess I just have acclimated to it to a different degree. Stuffing mags on the ground doesn't quite suck as much as swinging a hammer 30 feet in the air with a ton of tools and fasteners and belt hanging off your ass, not by a long long way...
