This is the best backpack ever, and I am someone who would know! I am a 36 y/o research scientist, mom and world traveler and I wear a backpack to work every single day, in addition to taking one on every trip and vacation I've ever been on. My favorite backpack before this was also in the Thule line (the crossover). I had it for 3+ years and I actually still love it. Before that I have used Ogio bags, Burton, Jansport, Camelbak, Osprey, you name it. For the price, this backpack really does have it all (well, almost).I mentioned that I use it for work. The laptop sleeve fits my HP Spectre X360 15" laptop perfectly. I LOVE that you can insert it in the sleeve at the top/inside of the bag but can access it via a zipper on the outside/side of the bag as well. I also keep my iPad Air 2 and all of my iPad and Laptop accessories and chargers etc. inside. I also keep my large wallet, a powerbank, my Sennheiser PXC 550 wireless over ear headphones, my lunch, and plenty of pens, cables, highlighters and personal stuff as well as keys and a water bottle etc. I also do some audio and video recording on the side and can fit a small tripod, Canon Vixia, my DSLR and other audio/video/photo gear in here if I want to. You could also easily fit a change of clothes in here for an overnight trip if you don't want to pack a carryon.I adore the colors of this bag and that it has a pocket or pouch for everything I need. My favorite part about this backpack that makes it different from literally every other back pack I've owned is the addition of the strap on the back for slipping it over the handle of a piece of rolling luggage, so you don't have to wear out your back/neck and shoulders wearing when traveling. It's very very comfortable, but even the most comfortable back pack is going to cause neck and shoulder pain after a long day of airports. This little feature is seriously my new favorite thing!!!The other "best" thing about this back pack is the quality. Thule doesn't skimp on quality. Period. I can speak from years of experience. I also own their large rolling luggage and it is my favorite by far. Their limited lifetime warranty is phenomenal. When I owned their crossover backpack, 3 years into my first one and a zipper started to come apart from the fabric of the bag. I contacted them and within the day they had shipped me a brand new back pack at no cost to me and with no questions asked. That kind of customer service is worth its weight in GOLD!! This bag is made for the long haul and is super sturdy with the finest materials from the zippers to the handles.The only complain I have about this backpack is that it doesn't stand up on its own when I set it down. The way it's made, it always tips forward, no matter how much or how little I have inside. It's a very rigid material for a backpack and I don't see it softening up and sitting flat over the years but I could be wrong. Also, I've always hung my back packs on a hook on the wall, but the way the top handle is positioned, it makes hanging it on my old hook impossible as it's too far forward on the bag and the space is too narrow in between the handle and the bag. Those are very minor quibbles though.In summary, this is the best bag for work, every day and travel that I have ever owned and I am NOT sponsored or compensated by Thule in any way for saying so! I've paid full price for all of the stuff I've ever bought from them, this bag included! I can highly recommend this for professional working adults, college students or travelers. You will not regret buying this. You DEFINITELY get what you pay for it and then some!
