The pack is under 2000ci, but as it's wider at the top than on the bottom it's actually a bit more than the 1463ci that the listed numbers add up to. When you add the two large side pockets @ 180ci total, I think it's pushing 1700-1800ci total storage. There is an internal pouch that covers the inside of the pack that rests against your back. I placed my poncho liner and a few maps as well as a legal pad for making notes. I put two MRE entrees in each of the side pockets, which are designed so that you can place skis or other items behind them for easy carry. I put my takedown longbow behind them, half on each side. Inside the pack I managed to put a 1 gal ziplock with my personal hygene items, a 1 gal ziplock with coffee, tea, sweetener, powdered creamer, emergency electrolite replacement drinks, a couple of instant soup packets and some salt-pepper-ceyenne-onion-garlic packets, a pouch of parched corn meal, Extra medical and medications, water filter and purification tablets, Becker BK-7 with kit in sheath, small garden trowel, TP, long underwear, 1 pair shorts, 2 pair socks, 1 longsleeve turtleneck, 1 pair pants, wool watchcap and gloves, leather gloves, 2 fire sources, 30' paracord, tin cup, backup compass, mil issue poncho. wool saddle blanket and a small saw. I carry my canteen w/cup + cover, stove kit and main medical kit on my belt along with a small buttpack containing another poncho and snare kit and I also carry an M2K on the belt. Anyway, you get an idea of what I was able to stuff into it. My Pad hangs off of it.
