Bought three for my daughters and myself because of the adjustability of the unit. Tried it on and fit beautifully. I’m not small, tried getting Xxl locally and they would not fit. Hold a 6 m4 and 6 pistol mags. Plenty of room to add extra pouches or pistol holster. Best part of this transaction though is the speed. I ordered multiple items on a Sunday night, got confirmation on Monday and package on Tuesday with free shipping. These guys are the best. Will be purchasing much more from them.
