Here are 3 pertinent words come to my mind to describe this bike bag. 1. Classic 2.Functional 3.Durable As the seller but also a cyclist, I recommend the bicycle bag. As you can see from the picture, the main body adopts black, match up with the （Blue，Red,Green,Gray） trim strip, zipper heads . Makes the overall design be classic without losing vigour. You could find the surface of the bicycle bag is textured if you look it carefully. The material called Polyurethane, which is a material usually used for imitation leather. It??s water resistant and anti-dirt. What you need to do is pour a little water on the surface and erase lightly when something soil the bag. Not like normal bag, the bike bag has firm shape, surface feels smooth when you touch it, and it features anti-impact. Inter layer EVA foam plays a buffer role, could well protect your items which be placed in the bag. Lining 210D oxford cloth is of anti-stab, prevent keen items from stabbing the bag. Top phone case has Less than or equal to of 6.2″ screen, Inside magic tape can fix the phone firmly and prevent it from swagging. Double zipper heads allow your earphone wire pass through the zipper. So allow you riding and listening the music at same time. Front end glare shield could avoid the screen vague problem which brings from reflective light. The price of the bag may be higher than competitor, but refer to its appearance and performance. Quite a high-cost performance product. I insist on the point that it’s one of the bike bags on the current market. Recommend it again.
