Familiarity: I've put it through the wringer
I recently purchased this pack upgrading from a smaller volume Osprey. First off, after years of riding with Camelbak packs...a friend suggested I try Osprey. I really like their packs.
This pack has just enough bells and whistles to make it really useful. The access to the innards is made simple by a couple well placed zippers. The 3 compartments make it really easy to carry everything I need for 2 hr, 4 hr, and all day rides. The main compartment (where the water reservoir is contained) is big enough for extra clothes. I use the left side secondary compartment for tools, CO2, pump and tube (for a spare). The right side secondary compartment is just the right size for food, etc. The helmet dock on the exterior of the pack is very useful.
Bottom line, love it.
