TAICHI RSB278 Motorcycle Backpack 25L Waterproof Roll-Top Touring Adult Black

[Safe even in rainy weather] The main air chamber is waterproof, so you can use it safely even in rainy weather. [Prevents water from entering] The opening is a roll-top shape, which prevents water from entering the interior and allows you to adjust the size of the bag to suit the amount of luggage you have. [Easy to separate small items] The front and zippered outer pockets make it easy to separate small items. *Please note that the outer pocket is not waterproof. [Reduced shoulder strain] The chest harness improves the fit to the body and prevents the shoulder straps from slipping off the shoulders. The waist belt also distributes the weight of the luggage, reducing the strain on the shoulders. [Consideration for safety at night] Reflective material is used to ensure visibility from behind.
