If you're looking for a great all around pack to hold your laptop and a ton of gear, clothes, or work paraphernalia the Chacabuco is your pack. This is my everyday bag for hauling my laptop, work paraphenalia, or whatever. The laptop sleeve is top notch - easily accessible and well padded. The water bottle pockets on each side hold large bottles in place no problem. And my favorite little feature is the two small pockets at the top of the pack. One is lined for sunglasses/phone/ipod, and the other is really nice to have for keys etc... Also a nice elastic cord on the exterior for lashing on a jacket, and organizer pockets in the small exterior pocket. Patagonia went all out for the largest and most fully featured pack in their daypack line and didn't leave much to be desired.
