Marmot Whirlwind Backpack - 900cu in

While most compact day-hiking packs are nothing more than featureless sacks with shoulder straps, the Whirlwind Backpack includes Marmots plush, well-vented AirFlow Frame System. No more sweating through your shirt when the temperatures start to rise. Marmot also gave this lightweight backpack a front organizer pocket, stowable mesh flap, stowable rain cover, and waist-belt pocket to keep things organized and within easy reach.
