Size Chart

Please use a cloth tape to take your measurement. It is better to have a helper do the measuring in order to get accurate measurement. The circumference of the head should be measured at a point approximately one inch above the eyebrows, or at whatever point gives the largest possible measurement. If you find that your measurement falls between two sizes, choose the smaller size for this helmet.

Finally, a helmet that doesn't strangle me!

Comment: Working in an ER has me convinced that a helmet is the way to go. Unfortunately I bought my first helmet at an expensive American dealership and paid top dollar. It was heavy, and I was beat to death by the wind, causing strangling, clenched teeth and strained neck. Even a short ride would end in a headache. This helmet is 2nd one I got from Jafrum as the first one was not the right fit. The helmets crossed in the mail and I had this one in 2 days. It is perfect for me! It's light, it fits correctly and I am not being buffeted by the wind. Not only is the quality great but their customer service is absolutely top notch!

Comment: looks and feels great. the first one was too large even though i measured as per instructions. get one size down and its perfect fit. the shipping time was only 4 days to california from the day i ordered. also the BBB rating influenced my purchase.



Solid helmet

Comment: Fast shipping, very pleased with the experience. The helmet is great for the money, a little thicker then expected, but exactly what I was looking for. I trust this company...

Great looking helmet

Comment: Wasn't sure what to expect when I ordered this helmet but was pleasantly surprised was it's good looks and fit. Will probably get a quick release strap because I really don't like the D-ring type.

Great Motorcycle Helmet!

Comment: Best bang for the buck! Fits awesome, is nice and light and it looks great. This is a Fiberglass Helmet, it just looks like carbon fiber but it is still a great deal.

Helmet nice fit

Comment: This helmet fits nice and low on your head. Some of these style helmets fit high on your head. Dot too!

The Best!

Comment: I bought this helmet after having owned both a Harley full and a Harley half. I really disliked them both. I read about the carbon fiber helmets online and thought I would give one a shot. I could not be more pleased than I am with this helmet. It is not big and bulky, it is very comfortable and does not have your head bouncing around at 80 mph like a bobblehead doll. I usually ride without a helmet and only bought this because I was going on a trip through a state that requires one. I just may wear it all of the time since it is so comfortable. I rarely write reviews, but felt the need to on this purchase. This was money well spent!

Can the "HCI" on the back of the helmet come off?
A shopper on Nov 16, 2014
Best Answer: Have not tried to take it off but it looks like a decal, not painted on. FYI love the helmet and will be purchasing another similar to it. Highly recommend!!

Will bluetooth speakers fit inside this helmet?
A shopper on Mar 25, 2015
Best Answer: This style helmet fits very snug to the head, there's not much room for Bluetooth speakers unless they're very small and almost flat. You may be able to cut some of the padding from inside the helmet, but that might compromise the integrity of the helmet...I don't know. I can tell you that I normally wear a baseball style Harley cap under my half helmets, but with this helmet the most that will fit under the helmet is a bandana. I bought my helmet accordingly to the sizing directions from Jafrum, helmets are supposed to fit snug on the head and not have a lot of "dead space" if you buy larger to accommodate room for speakers, then the helmet isn't going to fit properly in my opinion.

how thick is the padding inside?
A shopper on Apr 9, 2015
Best Answer: It's about an inch thick. It's a nice helmet but don't think it's going to look like a non-DOT brain beanie it still makes you look like you have a mushroom on top of your head.

One guy in his review said this is not a true carbon fiber helmet..just looks like this true?
A shopper on Feb 23, 2015
Best Answer: Seems to be carbon fiber by my understanding of the look, lightweight, and initial feel. I can understand the apprehension may be I lieu of the price point.
