The Brayden backpack is crafted using 100% recycled nylon for the shell and 100% recycled polyester for the lining, making this bag more eco-conscious than using virgin materials. The special ultrasonic onion quilting on the outside adds a unique detail to this backpack. Enriched with refined details, the backpack features interior and exterior pockets, adjustable compression buckles on the sides, and a back panel with quilted air mesh for breathability and comfort.
