Great Helmet!

by - verified purchaser
I finally decided to try getting over my claustrophobia and try a full-face helmet. I love my Gmax 3/4 with the pull-down visor and the exterior sun screen. However, my eyes always watered (for days after a long ride) and my motorcycle has a lot of chrome on the gas tank that is almost blinding if the sun is high in the sky. I wanted another Gmax since I need an XS and my old one fit so well. I called Jafrum and they were very helpful and directed me toward this one. Ordered it on Thursday and got it on Saturday. I don't like that no one will let you test ride a helmet and let you return it if you don't like it, but I get it, I guess. Luckily, this helmet was near perfect. I really like the interior sunscreen. Cheek pads are a little snug, but I'm sure they'll compress somewhat after breaking it in. I was also worried about wind noise but it was not bad. My eyes did not water and no glare from the tank. After an hour or so, I got used to the closed-in feeling. Glad I made the leap and I really think I'll like this helmet.

purchased this for my daughter, over all is a good helmet. Fits her good, she likes the internal sunglasses, i liked the light in the back but after using it one time it stopped working. Plan on taking a look and see if its just a battery, besides that its a good helmet for the price.

Had A Good OOPS

by - verified purchaser
When my helmet arrived I noticed the box was wrong and upon opening it the box was correct and they had sent a GMax 54 instead of the GMax 67 I ordered. I loved the look and feel so I called Jafrum and after explaining the error I explained that I wanted to keep the GMax 54. It was no problem to pay the difference AND my honesty got me a VERY nice discount!

Great helmet for price. The helmet fits just right, and the flip down inner shade shield is easy to work. Helmet quality is better than I expected.

Excellent Helmet

by - verified purchaser
Measured head and used chart. 23" so I went with a medium. Got it quickly and found it fit great. Never thought I'd be excited about a helmet but it has tons of features and is very comfortable. Got white for visibility but am going to order a flat black one too. The slide down sunvisor is great too. Highly recommend it~

Good quality, good price

by - verified purchaser
I purchased two of these helmets, one for me and one for my wife. I was concerned about sizing, given what some of the reviews said. We did the careful measurments, using the size chart provided here. I got a large and my wife ordered the small. When they arrived, the sizing seemed just about right. My helmet is very comfortable. I wear glasses, and it is nice to be able to open the front and put the helmet on without taking off my glasses. The fit is snug as it comes down over my ears, so it took a time or two before I could get it on without knocking my glasses off, but now it's all good. My wife's helmet seemed a little snug to her, although I can't imagine she would need a medium. At any rate, it turns out you can order different size cheek pads, so I ordered the medium size pads for her. They have arrived, but we haven't tried them yet. The pads come in 5cm increments, if I remember correctly. The clarity of the visor is outstanding. It makes me want to be really careful about not getting it scratched up. And the cloth bag that comes with the helmet is good for protecting it too. I haven't had much of a chance to use the drop down shaded visor, but it seems to be easy to access with a gloved hand, and it doesn't hit my glasses on the way down, so that's good. Overall, I'd say these are good quality helmets and the price is very competitive.

love the helmet. it fits me well. the chin bar works easily with one hand while wearing gloves. the flip down tinted lenses are great especially when riding at sunrise and sunset. the led lights on the back should help other drivers to see you better.

Great Helmet!

by - verified purchaser
I just purchased a Can-Am Spyder and was looking for a quality helmet that would protect my head but I didn't want to spend a lot of money. I got this helmet and was impressed with the quality and features. The flip up face piece work great and the sun visor is great also. I order a medium after measuring my head(22 3/4") in accordance with the instructions and it seamed a little tight so I shipped it back and and exchanged it for a large and it fit much better. I would recommend going one size up from what size you come up with from the chart. It is not cheap to ship back. The exchange went ok. Took up to a week to get back because they were out of the flat black large, but they cane in within that day and shipped back quickly. Overall great helmet for the money.
