First of all, the Nimbus Ozone is much more than a "weekend" pack - I used one for the northern 1000 miles of the AT (Port Clinton to Katahdin) after getting tired of sore shoulders with the GoLite Trek I started with. 3800 cubes is enough for gear plus 5 days of food and a 2-liter Platypus. For me that's 22 lb + 12 lb + 4 lb = 38 lb. (Granite Gear's Ultralight packs of comparable size are rated for 30 lb loads.) Compared to other heavier packs of similar size and 40 lb weight rating, the Ozone's 3 lb pack weight is a tradeoff I'll gladly make, because every ounce counts when you're on a long trek. You can go farther, be less tired, and reduce the likelihood of chronic foot and knee injuries if you reduce overall pack weight, and the pack itself weighs more than any item within it (unless you have a heavy tent). With the Nimbus, you have to forego features like a detachable fanny pack top, access zippers, and assorted compartments, but not durability - my original Nimbus Ozone is still holding up well after 1800 miles. It's comfortable even with a full load of food, and convenient enough for my taste.
