This is the biggest pack I currently build. It was designed to replace a customers old Dana Designs Astroplane, which was rated at 120L, but in real life wasn't THAT big.
Unless your military or hunting in the backcountry I don't see a need for a bigger pack.
despite it's size this pack, with it's roll top bivy closure is 3 lbs, 4 oz, the lid is 9 oz, and the alloy frame stays are 6-9 ounces depending on the final length. these weights include the sewn on front pocket, wand pockets and a ballistics nylon double bottom and lower rim.
This pack is deeper front to back, 10" on the bottom, to keep it from getting to tall. the owner of this pack is only 5'1" and 110 pounds. she has a 15" torso, so the back panel looks huge but overall main pack bag height is 29". I'll switch the photos onec i build a more average size. It also has much less taper, just 1.5", to make loading easier.
This pack has a new, big,simple, boxy lid with a huge 24" long #10 YKK waterproof zipper opening. there is a full map pocket on the underside with #5 waterproof YKK zipper. it also has 2 daisy chains on the top that run to ladder lock buckles to compress the lid if it's almost empty. lid volume is 9 liters.
