I think I love this, but I don't own it yet. I want it.

I've worn this backpack outdoors, indoors, in the city, in the country, at the beach, in the snow, in the rain, and in the sun. The pockets are big and useful - there is room for anything I could imagine. I've stored my laptop, books, clothes, and food in this laptop without any mishaps. The extra investment in a good backpack like this one is worth it - it will last and ensure that whatever you carry makes it safe to its destination.

I own this backpack and it was one of my best purchase ever. The water bladder is contained in a flat, padded compartment and does not shift around, which is important, since water can cause unstable weight distribution. For long hikes, you want stability. I used this for Burning Man (you have to bring your own water), and it was awesome. The backpack is small (for bike riding) but it has a ton of compartments so you can store all your needs, flashlights, goggles, extra clothing, walkie talkies, pen, paper, ipod, make-up... Lots of very well-thought out elements to help organize your stuff. (via msr41)
