This "Flower Power" backpack by Dabbawalla Bags is constructed entirely out of durable neoprene, the great material that wetsuits are made with. Neoprene protects, insulates, and cushions without worry of lead or other bad-for-you chemicals. Unlike conventional kid's backpacks which are often stiff and oversized, Dabbawalla backpacks are soft and sized for comfort. Machine-washable (lay flat to dry) and stain-resistant. Well-designed features include cushioned handles, reinforced seams for added strength, wide zipper openings, and inside pockets for stashing gear. Cushioned, flexible straps that adjust from the inside can be pulled tight when not in use - no dangling straps to trip over or drag. Outside back pocket. Three inside mesh pockets. Dimensions: 13"Lx10"Wx7"D
