From the manufacturer

When work and workout share the same day, this 28L Amplifier backpack carries the load. A roomy main compartment comfortably carries binders, notebooks and a change of gym clothes, with an interior sleeve that securely stores a 16-inch laptop so your tech rides protected. Multiple zippered pockets keep chargers, snacks and small electronics sorted for fast grab-and-go access through commutes, classes, study sessions and after-work training. Padded shoulder straps and a supportive back panel ease all-day carry, and two stretch mesh side pockets each fit up to a 32 oz water bottle. Built from durable polyester with a wipeable interior lining that cleans up with a damp cloth, and reinforced stitching that holds up through years of school and work use. Measures 11.25 x 8.25 x 18.25 inches (L x W x H) — a tall, streamlined silhouette. May fit under some airline seats; check your airline's personal-item dimensions before travel. Sized for high school students, college students, dorm move-ins, commuters and active adults across the daily school carry, daily commute, gym rotation and weekend rotation. Backed by the Lifetime Warranty against material and workmanship defects for 5 years, the typical life of a well-used bag.
