Eagle Creek Rincon 65L
Here's what other sites are saying:
Breeze over to the airline counter with the Eagle Creek Rincon 65L Travel Pack on your back. Then detach the 20-liter daypack and hand the main pack to the baggage check peeps. Stash your boarding pass in the daypack's zippered back-panel pocket, shoulder the daypack, breeze over to the gate, and get lost in a book until your flight is called.
If you want to be mobile, comfortable, and organized while on the road, the Eagle Creek Rincon 65L Travel Backpack is the pack for you. When you detach the removable daypack, it counts as two carry-on sized bags - one for the overhead, one for under the seat. You can even attach the daypack to the front of the Eagle Creek Rincon 65L, so you have easy access, better security, and better weight distribution.
