I bought this bag mainly because it pretty closely fit the dimensions for an under-seat bag on Lufthansa Airlines (which is incredibly small) and for the fact that it could convert from a backpack to a crossbody to carrying it as a tote bag. I recently took this bag on a 10-day, 3-country trip through Europe and it held up fantastically.10 Stars to Sherpani for the lime green interior lining!!!!!! Most bags use a black interior lining and it is like looking into a black hole. The lime green interior made it easy to find things, even if they were at the bottom.Another 10 stars to Sherpani for the deep side water bottle pockets!!! I could bend over with the backpack on and my water bottles didn't fall out. In addition to water bottles, the outside pockets fit an umbrella or a pair of foldable headphones.There is a lot of room in this bag. Inside the bag, I had a 9x10 travel purse which had my phone, 2 pairs of glasses, passport, billfold, tissues, comb, lipstick, chapstick, and mirror. Also in the main interior pocket, I had several chargers, face masks, 2 pens, medicine, a bag with feminine products, and a makeup bag. In the two zippered outside pockets I had medications, tissues, gum, mints, earbuds, and a couple of snacks. I clipped my travel pillow on the bag as well. The luggage handle sleeve was also a bonus. Once we arrived at our destination, I took the purse out and mainly used this bag as a backpack for day trips and sightseeing with plenty of room for souvenirs, hat, gloves, etc.It rained on us almost every day and the bag held up beautifully. 3 other women in our travel group saw the bag and promptly ordered one for the same trip.My only concern with this bag is that the clips for the straps seem pretty flimsy and I was worried they might break during the trip. At this price point, this bag is competing with Travelon and Baggalini bags which have much sturdier carabiner clips with safety locks. I'm surprised given the other safety features on this bag that Sherpani hasn't upgraded the strap clips. Overall this is a great bag.
