I wish more people would write down what size they have in their reviews.

On a recent 10 day trip to CO I packed a 42 liter pack inside my Large base camp duffel, and all my backpacking essentials– sleeping bag, filter, hiking shoes, nalgene, stove, camelbak, etc; 5 days of clothes including two warm layers, climbing shoes, harness, some draws and belay devices; and even threw in a couple of books in the internal mesh pocket.

Everything fit fine, airport weighed it in at 40.5 lbs. The straps work wonderful going down flights of stairs to the car. And going from curbside to check-in. Handy little tip: when you are about to check it in cinch the backpack straps all the way down and use the velcro tabs (under the TNF logos) on the straps to hold the excess strap material. You don't need to remove them!

Look forward to using this bag for a very long time.

Like the other viewer said, yes this is the bmw of packs but at honda pricing! I've used this primarily as a day cragging, bush wacking, tree scraping daily pack and it still looks brand new (after I wipe all the chalk/dirt off of it). I've also used it up to 30 mile 4 day/3 night UL trips with no complaints- but be careful your overpacking 60l buddies will loathe you! I've put this thing to the test for the past 10 months and I can safely review this thing.

It fits like a dream on my medium torso and you don't always have to mess with the settings. The air-comfort mesh panel is genius and with a light enough polyester shirt and a perfectly aimed breeze you can actually feel cool refreshing air on your back. All of the pockets and features are great on a pack this size because it helps you organize and situate the load properly.

Like the title says I don't know how deuter can offer such an awesome pack at a great price, but I think part of it is because they are really popular in across seas and are probably trying to make a mark on the US market. I'm sold and can't wait to buy a bigger deuter for extended trips, which are even more of an awesome value!
