Osprey FLAPJACK PACK

This backpack is great as an everyday use backpack. It is simple but well designed. What I love: 1) comfort; 2) it is wide and deep but slim going from your back outward, which makes it sleek; 3) lime green inside, which makes items easier to see; 4) good for travel since the flap provides a cover for interior pockets making it feel safer and the pack easily fits under an airline seat, even the smaller spaces. My husband steals it to take to baseball games on the weekends, and he likes it for its comfort as well. Fits both of us no problem. I'm 5'4" and he's 5'7". I tried to pack it for an overnight (shorts, shirt, t-shirt, underwear, slippers, toiletries, jacket, ipad, charger, phone charger and small gift box) and it was just a tad too small so I had to switch to my messenger for that. So the only downside is that although it is sleek, you sacrifice on volume.
