I've had this bag for over 4 years now and it has been a constant companion on several trips.  It's amazing how much you can pack in this bag.  Enough for a week in Hawaii and several 3-day weekend trips.  I love this bag over spinner bags because it's nice to have it attached to myself when solo traveling.

Pros: Size, durability, comfort when wearing, nice canvas backpack, great for adventures

Cons: the front pocket just snaps (I do not keep sensitive items here).  The bag is big and things can get lost at the bottom or hard for easy access when at the airport or on a flight (remedy is just some organized packing).

For the organized packing over the past two years, I've used my packing cubes in the backpack and it has helped out a lot. I totally recommend this bag :O)
