Awesome helmet

by - verified purchaser
I have always used either HCI or Fulmer helmets. I decided to give the Gmax GM55S a try. This is by far the best overall helmet I have ever owned. As soon as it arrived I put it on and rode for over 50 miles. I hardly knew I was wearing a helmet. It is very light and comfortable. Great buy!

I don't generally wear a helmet, but when I do...I wear this one. Being deaf in one ear, the configuration allows me to hear very well. Good quality at a good price.

Just what I was Looking for!

by - verified purchaser
I have wanted a half helmet for awhile and finally found the one I was looking for! The fit is perfect and the detachable neck curtain is definitely a bonus! The padding is awesome and the low profile doesn't give you the "mushroom" look. This company offers more gear/accessories at a better price...and I have compared!!! I WILL be a return customer to Jafrum!!!!!!!!

Just As Expected

by - verified purchaser
The GMax GM 55S was just as advertised. Thought I needed a large but read reviews and ordered a size smaller. The medium fit perfectly. I ordered the yellow visor for night time riding and I think it will work perfectly. The weight is great, much lighter than my Bell. Product shipped as promised and received a day sooner than expected. Will definitely shop Jefrum again. Awesome service.

Nice helmet, good buy

by - verified purchaser
Borrowed a friends half helmet to try. I liked it for short rides around town, but helmet was a little heavy. I shopped around and found the Gmax GM55s would suit me better. I ordered the XL. When it arrived, it was a little too tight. I returned it to Jafrum who mailed back, at no charge, the XXL. It fit great. Lightweight helmet with sun visor at a good price. I hope I don't have to test the crash worthiness. Jafrum was a good company to deal with. Easy ordering, quick response.

GMax GM55S Half Helmet Review

I was looking for a good solution to being able to wear my prescription glasses which I only need at night. Goggles take too much periferal vision away for my liking so I ordered the GM55s and the clear shield to replace the sun shield......Perfect! Combine that with the fact that the GM55S is A LOT more comfortable than my HD brand bucket. Once again JAFRUM delivers with good quality, affordable solutions that show up FAST.

Great helmet, see a lot of comments about the retractable visor don't come down far enough, all you have to do is push up back of helmet or pull Down front, at times this makes a world of differents in a down pour.

love the helmet. visor provided shade from glare of sun in the early morning when riding into the sunrise. also provided protection in heavy rain. used it for the first time in a 5000 mile round trip to Sturgis. great price also. would recommend this helmet.

Awesome Helmet

by - verified purchaser
Helmet is awesome! It fits great and the extra liner is really comfortable. The regular liner does not attach in very well but it is manageable and, for the price, it is not a deal breaker at all.Granted, I just use it for in town traffic (no long trips or interstate) so I might not be the best one to judge whether or not to purchase. I have a more heavy duty helmet for that.

This is my first helmet for my bike and it is a great helmet. I bought matt black and looking sleek! It does the protection but give you little bit of Mushroom head, but I can deal with it. Everything's good except for one thing! Instruction for changing visor is not described well and I am having hard time trying to change the visor!. But my overall rating for this price is awesome!

Helmet was OK, but...

by - verified purchaser
I have a massive cranium apparently, so when I measured my head I went to for the XXL and it was a little too small and the visor was goofy. I am betting that the prototype for this helmet was for the regular head size person. Great deal for them, I'm sure. Gotta keep on looking Big Heads out there.

Why did you choose this?
Jafrum Store
Going to Americade in Lake George, NY next week and need glasses to block out wind on long ride. Use regular sunglasses now and airflow into eyes is annoying, even on short rides. Reviews sounded good, so I am trying smoked and clear lenses for long ride.
