I bought the OG shell bag over a year ago and have taken it on so many trips I've lost track. I don't write reviews, but this bag has been rock climbing in Greece with me, ATVing in Mexico, sightseeing in countless cities, and probably close to 100 plane/train rides. The versatility and convenience of the kangaroo pouch is unparalleled to any other backpacks I've had and I still have ppl look at me when I easily take the front pouch on and off before or after flights. It has quickly become my favorite backpack I've ever owned and I look forward to many more memories with it.
