I bought this bag as my first ever traveling back, I went to South Korea for a two month vacation and it was amazing, comfortable, the back was nice and airy so I didn't have to worry about sweet and it kept its nice coloring too! During out trip we went through four plane rides, one island, hiking and we brought home glass bottles in it wrapped in cloths and not one of them broke. I used suction seal bags for my cloths but I brought 5 pants, 6 shorts, 4 bathing suits, 15 tops, 4 dresses, hair products, charges, my laptop, hygiene products, and two pairs of shoes. It all fit and was able to still tighten the bag. The straps are easy to adjust and even if it take a little time you will find your perfect fit with this bag. I gave it a 100% because I couldn't find one fault in it. I'm headed back to Korea for a year this time and will definitely be buying another one of their travel back or luggage products.Bought this backpack to use as a bug-out/earthquake bag. It's great for this purpose. The 55L size fits all the stuff I need for a 3-day bug-out. The quality is usual JanSport -- first-rate! The support system is adjustable and excellent. There's lots of compartments for storing your stuff -- all where you want them for easy access. I paid $99 for the pack, which was a great value. There's cheaper bags out there, but do you really want to risk discomfort and bag failure in an emergency?Cons: none that I can think of.This backpack would also make an excellent bag for travelling in Europe.
