Osprey Transporter 60

Its usually pretty tough being a middle child, but the Transporter 60 doesn't seem mind.  Osprey made the Transporter 60 extra beefy by bulking it up with an additional 1000 cu. in. over the 46.  This 3600 cu. in. interior has internal organization to keep all your gear in order, and the bag was given an extra end pocket in case one isn't enough.  And like the whole Transporter series, the Transporter 60 has a 1680 denier water resistant bottom to keep your gear dry and protected.

Dimensions:
23" x 16" x 10"
