It's a very handsome backpack. It fits my 15 inch laptop, bike shorts, regular shorts, t shirt, and two tupper ware containers for lunch just about perfect. I could fit my size 12 dress shoes instead to lunch and it would be real right. The pack is hot. I've been riding after work but its been over 80. It's hotter than my camelback but it's bigger so whatever I'm working out. Aside from the heat it's very comfy. The shoulder straps are floral good. I'm 6'4" 240lbs and it feels just right. I don't have to buckle the chest strap and it's perfectly snug even if I jump a pot hole. I bounces less than the camelback. So yeah I feel like a real hipster wearing this pack. It's so pretty, functional and sturdy.
