You Can't Beat The Quality For The Price.

by - verified purchaser
I put this helmet on my Christmas list, I was fortunate enough to have my wife buy it for me. I thought I would use this helmet on my side by side, and also in cold weather when riding my bike. I've used it for both, and can't be happier with the results. The face mask retracting all the way helps protect the shield as well as keep it out of the way when you don't need it. the fit and finish on the helmet is excellent and you can't beat the price.

GMax GM11D Adventure Dual Sport Helmet

by - verified purchaser
I just purchased a Honda XR650L Dual Sport and needed a good off-road helmet, I ride a Harley most of the time. I researched several Helmets before purchasing the GMax GM11D and I am really pleased with it. For the price I think its one of the better Helmets for Dual Sport riding. I really like the shield so you can wear sun glasses, when it gets dark out take the glasses off and your still legal. Great looking Helmet, and I received it sooner than expected. Great web site will be a return customer.

Nice Looking Helmet

by - verified purchaser
Nice looking helmet with nice features for the price. Shipping was very fast. They run small though. First one I ordered, following the sizing chart and measuring my head exactly, was too small. So I gave that one to my wife and ordered a larger size. It also shipped fast. The larger one fit perfectly. Visor is very easy to remove as well as the shield. Vents are easy to open and close with gloves on. Cheek pads are pretty tight though.

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

Very Good Helmet, Great Service

by - verified purchaser
Got this helmet just a few days after I had made my order, using the free shipping. Have put about 500 miles on it, its a great all around helmet that has lots of adjustments to fit any user, would recommend this so far. If your thinking of buying, I strongly encourage this as your choice.
