☀ LARGE CAPACITY:The motorcycle rear seat bag has an expandable bottom to expand the storage space. The maximum size can reach 29*30*43cm/11*12*17in, which is enough to accommodate full-size helmets and other bulky items. And it folds up as designed when not in use, but when it's full, it expands to nearly double its original volume.
☀ HIGH-QUALITY MATERIAL: The motorcycle tail bag is made of high-quality Oxford cloth + carbon fiber, which is waterproof and can also be used in rainy days. And when it doesn't stow the helmet (not unfolded), it's rigid enough to keep its low profile shape and look great on the bike.
☀ VERSATILE USES: You can attach the motorcycle tail bag hard case to the motorcycle, or use it as a handbag and shoulder bag for easy mobility.
☀ SURFACE SAFETY DESIGN: The reflective tape on the front of the helmet backpack ensures safe riding at night. Two-way zipper for easy access from all angles. There is a hook and loop sticker on the outside where you can put your mask. The outer layer has an elastic cord mesh design, which can be used to keep wet raincoats.
☀ EASY TO INSTALL: This package can be easily installed in just four steps. First, open the seat cushion. Second, put the straps on it. Third, cover the seat cushion. Finally, put in the helmet pocket and fasten the shoulder straps. When you put the bag in the car, you won't notice it because it is very stable and secure. Even on the highway, the bag stays firmly on the back seat and doesn't fall off.
