Material Quality is ok, windproof, and hope it's waterproof too. Soft layer inside 👍. 2 zip system for easy & fast closed/open 👍. It would be good and practical if sling can change to the other position during we are walking or riding. Existing sling rope only suitable during walking only, if we use it when riding, bag will move in the left/right of our body. Please consider when we ride with it.

Feels Solid and protective of my helmet. Very portable

Great quality
