Great Helmet !!!!!!!

by - verified purchaser
The main reason for purchasing this helmet is the face shield goes all the way open! I bought a tinted face shield as well looks nice and has a kind of rainbow color to it when light hits it. Overall I'm very happy with my purchase and happy with Jafrum's quick delivery

Best Answer:No, I did not get one. I bought two helemets ( one for my kid ). I also bought two sena 10 communication systems and happy with both. I like the helmet for the price but it does fog up with a 50 degree day fast (same with most helmets).

I bought my Gmax GM11D abd I'm very happy with it. Helmet is great for my quadbike off and on the road. I use sunglasses most of the time with visor wide open and visor closed at higher speeds on the road. Only problem is a rain and fogging. What option would you recommend. Get a heated shield for the helmet or a googles?

Thank you for your answer.

Best Answer:Never used a heated shield and not sure how well they work. Goggles would work because they get adequate air flow and would work better off road. They also make a anti fog spray. It's pretty dry here and not a lot of rainy days but it's the 55 degree days and below that fog up my shield. I just crack the shield open slightly and that clears it right up in our dry climate.

I did install a Sena 10 communication system and can control my smart phone from my helmet which has worked out so well I bought my kid the same set up. Good luck.

How do I know my size?
A shopper on Mar 17, 2015
Best Answer:There is a size guide on the web-site. It worked o.k. for my wife's helmet but my head shape must not be

generic as I had to exchange for a larger size. I think my face is wider below my ears or something, but Jafrum is very good about exchanges only you will have to pay the postage to return it.
