MASSIVE! I currently have two vests with pouches and pistol holsters, full set of ACU's, Echo1 Timberwolf, M4, Echo 1 MTC, MP7 with holster, Propane tank, BB's, knee pads, goggles, two small screw driver and allen kits, silicone, a couple mesh masks, and there is still room for more!!! The backpack straps make this bag even more amazing. And its surprisingly comfortable still. It's a must have, trust me. The only thing that kind of sucks is that there is only one pouch for all the things you dont want mixed in with all your gear like your goggles, silicone, red dot batteries, and small stuff like that. Doesn't really matter though.
Back pack straps
I can fit two load outs plus guns and extras
Its awesome being able to carry EVERYTHING in one bag and being hands free.
Just being picky, but:
Not much for pouches outside the bag
No molle straps to add more pouches to the outside
