This is Serious. This backpack is loaded with features and packed with amenities. With a water-resistant lining, each segment has multiple pockets including a padded sleeve to protect your 15 inch laptop or tablet, space for your media device with headphone access. Gosh books are getting heavy! Use the padded waist straps to relieve your back and transfer some of the bagâ€™s weight to the hips, and when not in use, tuck the straps away so that they are not dangling. Donâ€™t want to carry your lunch box? Use our convenient carabineer and strapping system to secure the lunch box to the back. Or, use the straps for your yoga mat or extra clothing. Tired of drinking warm water or soda? One of our drink holders is insulated and will keep your 20 oz bottle cooler, longer. The Serious Backpack is a smart and savvy option to handle the demands of school hallways, sports fields, and exotic adventures. Bring it on! One-year manufacturer's warranty against defects - normal wear-and-tear, and misuse excluded. Rigorously tested to ensure that all parts are lead-safe, bpa-free, phthalate-free, and conform to all rules and regulations set forth by the Consumer Products Spot clean with mild soap and water.
