Great Light Pack.
This pack is actually a lot bigger than 24L when you consider the AirCore space and the straightjacket straps. I put my hydration bladder in the AirCore space which frees up a lot of space in the pack. With this arrangement, I use this pack for ultralight, warm weather overnight/weekend backpacks. It really fits more gear than you think it can. The fit of this pack is a dream. It hugs me perfectly, with no pressure points. The hipbelt design keeps the pack secure, and takes some pressure off your hipbones. This is a great day pack, and a great warm weather ultralight overnight pack.
