I'm an ultra-light backpacker so I was jazzed to see this pack. I use a GoLite pack and wanted to see what Patagonia had to offer. Besides not being bladder compatible (sure, you could rig something up, but why?), it's narrow in design making it difficult to use for most backpacking trips. I returned it.
