Is this the 2011 or 2012 model?
Is this the Exploration System 3 model?
I'm ironically in the middle of a 9 day family vacation trip using my Eagle Creek Switchback Max 22. I LOVE THIS THING... & it has a lifetime warranty!!! :-) A much easier 11 block hike in NYC this morning with it packed heavy on my back to get to the rental car counter versus pulling a regular wheeled bag that far over the curbs, pot holes, and through hundereds of people. The removable smaller pack is just the thing to carry around the family's water, camera, band-aids, etc., all over town sightseeing.
As far as the model year, I obviously can't tell you which Sunny
Sports is stocking. Either model is a great investment and I'm sure you'll get more tired of traveling before it gets worn out!!! :-)
This is the updated model. Enjoy it! Zack.
