Colliding at the intersection of functional and fashionable, plus dropped weight and upped performance, is the Nike Cheyenne Vapor 2 Flash Backpack.
Part of the Flash collection, this piece of gear is constructed with material that reflects light so even in low-light situations, you'll be shining. That's not it though; this bag features a Nike Aerospan back panel for enhanced airflow and Nike Hypervoid material throughout for increased stability. The amount of storage you have with this is a bit flashy, too. There's a dual-zip main compartment with laptop sleeve, a zip pocket at the base for separate shoe or wet/dry storage, plus a 70 ounce hydration reservoir. Even if Mother Nature decides to rain on your party (or backpack), then the packable rain cover has you covered. So strap up (with the comfy adjustable harness) and take on the trails or streets head on.
