so, here you go, proof.
Left helmet is a large HJC 33ii Niro and right is a medium Shoei Multitec.
The 1st pic the Niro is in the bag.
3rd pic.....The pic posted with the Shoei and the shuberth helmets I saw somewhere on here that Shuberth looks HUGE.
So yes it’s a tight fit...but you can get two helmets in there.
EUREKA!!!!! I showed this picture to my buddy and he was able to get both his and her Shoei's in there. Next step is to get him to join the forum!!! Thanks!!!
