Kirk Severson wrote a review of Osprey Packs Quasar Pack - 1800cu in on November 30, 2011
I've had this bag about a year now and have no complaints whatsoever about it. I use it primarily as an every day bag between work and school. It somehow holds my 17" MacBook Pro in the laptop compartment as well as a couple books and papers without any problems. I also really like how this bag has a harness, which makes it perfect for use while riding a bike or a motorcycle.
It isn't totally waterproof by any means so that is one downside. Also, while I have used it for shorter dayhikes, I normally will use another bag for that purpose as this isn't by any means the best hiking daypack out there. Anyway, another fantastic entry from Osprey.
