I got my helmet bag for the first time, but until that time I put it in a suitable bag. There is only a dedicated bag, it is very useful without being unstable or unexpectedly scratching. Although it is subjective, there is no bad impression like other reviews, and it was quite affordable because it is cheap enough not to see elsewhere.
It was thinner than I thought, I thought that I could not expect much like shock absorbing function. As a member of the SHOEI party, design and so on are satisfying as the presence is batch. However, because fray of thread can be easily found, I think that inspection, confirmation etc are not done.
