Good Looking Helmet but...

This helmet sits high on your head so it makes it feel top heavy. The removable liner comes out when you take the helmet off. It is a good looking helmet in pictures and sitting on the shelf, I like the stitching around the edges. I just wish it sat lower on my head.

Gun metal gray

This helmet is very comfortable and fits me perfectly. The color is a very close match to my gun metal gray Harley.

Helmet shape

The rim is too big around the head and helmet moves around, not seated properly. I am very disappointed with my purchase.

Dinosaur egg head

I was expecting a helmet that fit good but didn't look like a dinosaur egg on my head. It looked exactly like that...lol. the second thing, I'm bald, I took it off immediately after lmao, and the inside padding stuck to my head, obviously I laughed even harder. After I wiped my eyes from all that. I packed it up and shipped it back. The outside (shell) seemed good, the padding not so much. Cost 10 dollars to look at a helmet for 10 minutes. I guess I paid 10 bucks to laugh at myself for a few minutes. .lol

T’is what it T’is.

Nice looking helmet. Comfort and fit are reasonable given the price. Strap width or D ring size/shape might be a bit off. Takes a little more effort to navigate. <br /><br />I just got it to try out the style see what it was like. Mission accomplished.
