Purchased the MTP version. Though you might expect the newest version to fit only on the MK7 helmet (which is restricted for civilian ownership), this helmet cover actually fits the MK6 GS helmet perfectly. It secures with a drawstring, and fits the appropriate size of helmet perfectly. For reference, I own a MEDIUM sized helmet, and the MEDIUM sized cover is easy to get on, and fits the shape and size of the helmet very well.

Pros: No signs of wear or damage, Easy to put on, Fits perfectly

Cons: none

Sizing: Feels about right

Would recommend: Yes
