I travel ALOT for work and I needed a back pack that would not only hold my essentials to enjoy a flight but also clothes for the next day. I’m able to fit a tolietry bag, clothes, workout clothes and my electronics all in one bag. With all that weight in the back pack, I don’t feel it on my back. It still feels light, and fits like a glove on my back. Not only does it hold everything I need, it also makes items such as passport, wallet, and keys easily Accessible. Very very comfortable. I love this bag.
