The grey waterproof Oxford fabric is used for the fabric part, and the inner pearl cotton has good shock absorption effect and enhanced resilience. The upgraded backpack has especially widened the width and thickness of the shoulder belt. The back is formed by a large piece of EVA, which makes the bag shape fixed and not easy to wrink. Besides, the back is widened and thickened with breathable cotton, which is breathable and sweat resistant, dispersing and relieving the force on the back, making the shoulder and back more comfortable during wearing. Enclosed anti-water cover protects the backpack from getting wet.
