All my products are 100% Authentic. Mesh material is used on the back to increase comfort when worn, and an antibacterial treatment is added to ensure high quality. The lower front pocket can store indoor shoes, gym clothes, etc. Both side pockets are made of clean fabric and are recommended for storing things like water bottles. It has a reflective logo print treatment for added protection at night. International Buyers – Please Note. I do not mark merchandise values below value or mark items as “gifts” – US and International government regulations prohibit such behavior.
