Generally, I carry fifteen to sixteen pounds which, with the Exos, means I'm carrying about 18 pounds for a weekend. Of that, I carry one liter of water and a pound of food a day - 4 pounds; another half pound is the small fuel canister.

I've carried 23 pounds in the pack, and noticed no real difference in the carrying comfort. Above 25 pounds, the suspension starts to "collapse" - the hipbelt won't stay put and I can't get the weight off my shoulders.
