Richard T.wrote a review of Granite Gear Nimbus Ozone Backpack - 3400-3800cu in on June 2, 2008
It's just a straightforward bag, with tons of room for anyone trying to travel a bit lighter. But it's put together beautifully, with all kinds of ways to make it fit just right for each individual. Very comfortable, even with a full (40 lb.) load. Only complaint is a lack of any pockets to put stuff you might want on the trail, but you can add one or more as an accessory. While it's quite light for its size, it is very strong and able to stand up to granite, etc., unlike the superlightweight options, which use less rugged material. Choose this pack for years of great trips.
