Fly 9MM Helmet Sizing

Helmet Sizing Information:To achieve proper helmet fitment, begin by finding your head circumference size using the method described below. Remember that the helmet sizing you choose should fit around the crown of your head comfortably with no pressure points. The cheek-pads should fit firmly around your face. Once your chin strap is fastened, grab the chin bar of the helmet and move it side to side. Your cheeks should move with the helmet, which should not slide across your face. Different thickness cheek-pads can be purchased to obtain the perfect fit.

Head Measurement Instructions:Wrap flexible tape measure around your head approximately on inch above eyebrows and ears. Use this measurement (in either inches or centimeters) to find your helmet size in the chart above

Fly 9MM Helmet Review

by - verified purchaser
This product was shipped precisely when it was suppose to arrive. Looks nice just as the picture. But the only drawback is that they don't have the size chart accurate. I order a 4x for extra room since a 2x fit me snugger than I would like but their 4x fits tighter than the 2x I already own. So I'm going to send it back for a larger size.

Fly9MM Review

The helmet came quickly and we all know Jafrum is a great company! The helmet fits however, it appears very large. The inner liner is very thick (1.25 inches) and I'm sure the liner is for extra safety but, it makes the actual helmet much larger..

I purchased the DOT German Style half helmet. The shipment arrived precisely on the date promised. The helmet looks great, has a very comfortable removable liner and the sizing chart on the web site was perfect. I'm very happy with the product and service provided by Jafrum. I would by here again.

Awesome Website!

Ordered my FLY 9MM Half Shell helmet over Memorial day weekend, with the holiday being that Monday I received the helmet on that Wednesday. Much sooner than I anticipated. I checked the price of my helmet before I bought and Jafrum had the lowest price. Fast amazing service. I had to email customer service about receiving my tracking number and an email was sent back within the hour. Product fits great and gets awesome looks, no issues with it at all. I would recommend new or veteran riders looking for great deals to buy from this company. I know I'll be back!
