Now let’s get Serious. With a water-resistant lining, this bag has multiple pockets including a padded sleeve to protect your 15 inch laptop or tablet, and a pocket 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 bag’s weight to the hips, and when not in use, tuck the straps away so that they are not dangling. Don’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 your drink getting warm quickly? One of our drink holders is insulated and will keep your 20 oz bottle cooler, longer. Bag measures 18 inches x 13.5 inches x 8 inches.

Features Serious backpacks are made of water-resistant, super-durable 600-denier polyester, and are lined with an extra layer of water-resistant polyester for extra strength and easy cleaning. A load-bearing, padded waist strap will relieve some of the heavy weight of books on your back, and when not in use this strap can be tucked out of the way and into specially-designed pockets. Padded, adjustable straps make for custom sizing and comfortable fit. Five exterior pockets will help you stay organized, and the utility pocket is a great place for pens and pencils and other small items. One of the exterior pockets is designed for a media device with a push-through portal for headphones, and the large main compartment includes a padded laptop sleeve large enough for a 15†notebook or a tablet. An insulated drink pocket keeps drinks cool longer, and the carabineer and external straps make carrying lunch boxes and other items easy. Available in many patterns, and can be matched with Wildkin lunch boxes and many other accessories. Designed for ages 10 and up.
