What do you do with your helmet when it's not on on your head? If you leave it with your bike it can be stolen or damaged. If you carry it around with you (aside from looking like a dork) you can drop it and damage it. This bag is great for avoiding these problems and protecting your helmet. Now if it only had a pocket for a spare visor.
Very useful to protect expensive helmets from scratches. Folds up easily to carry in saddlebags for use when traveling overnight.
Works great for large helmets, and is very easy to open and close with the wide opening.
