Deuter Speed Lite 30 Backpack - 1850cu in - 2009 BCS

It's light and tough. I use it now nearly for everything - backcountry, tradclimbing, hiking, city bouldering. If you tend to pure and plain packs with just one zipper probably you don't like all this straps. But it helps you through nearly every situation, even though you can feel like a cristmas tree if you don't put them in place. Also very robust. I love it!

It is not a bad pack for the money and the weight. It isn't very comfortable due to its very lightweight internal frame which only consists of a couple aluminum rods. Shoulder straps are very comfortable though. Sweat buildup is not bad for a pack with pads instead of a mesh. Dividers inside are nicely arranged. The hydration pocket includes a Velcro strap, not a loop, making it ideal for platypus, a PITA though for Camelbak and others that need to be hooked.
The biggest issue is the size. I have a torso length of about 21 inches, average if you ask me for a male. This causes the waist belt to sit at my belly button. If that's your thing, you'll like this ultralight. Otherwise it'll drive you nuts, the way it did me. I am selling mine after using it once!
