Nice helmet, and lite

Great helmet fits good and has mips like I wanted. Rode with it about 5 times nothing I don’t like about it. Padding comes out easily to clean.

Great helmet!

I've been buying and testing helmets (dirt Sampling) for 54 years. My first was a Buco with leather suspension, Have had many Bell's, Shoei's, Electro's and many others along this Moto-journey. This helmet is the best helmet I have bought so far. Light, cool and very comfertable. Price was at sale price and it is well worth the $150 I paid for it. Have not tested it with a soil sample yet, but I am sure it will protect my noggin with the MIPS system installed. Very Stylish as well. Great Job Troy Lee! I will buy another!

Killer deal

First MIPS style helmet i've had. Just recent;y got back into riding and i know i needed to upgrade my helmet. This thing feels great, lightweight, snug and comfortable. I highly recommend this helmet to everyone who doesn't have a mips style helmet and who is on a budget.

Troy Lee SE4 Polyacrylite Helmet With MIPS

I sent this helmet back. It was the most uncomfortable helmet I've ever worn, with pressure on the front of the skull. I own a non Mips Troy Lee helmet and love it, so I couldn't believe that the fit would have been so drastically different. No way would I recommended this helmet. If you want MIPS, look elsewhere.

MEASURING INSTRUCTIONS

1. Measure your head size. To do this, pass a tape measure horizontally around your head at a height of about one inch above your eye- brows. When done properly, you will have measured the largest part of your head.

2. Check your measurement with the helmet sizing chart and select the closest size. As the helmet may not always meet your head size exactly, and your head measurement may fall between two sizes, first try the smaller size.

WHEN YOU RECEIVE YOUR HELMET

1. Expand the helmet opening by pulling outwards on each chinstrap, and slide your head into the helmet. If you are unfamiliar with helmets you may be reluctant to pull the helmet down, as it may feel too tight. Even if the helmet is difficult to put on, please use the smallest helmet possible. The helmet should feel snug. If the helmet is not tight, it is too big for you. New helmets will break in and loosen slightly over time.

2. Once the helmet is on:

Check that the helmet inner lining fits snugly all around your head.
Check that the top pad presses on the top of your head.
Check that the cheek pads press up against your cheeks. When you open and close your mouth, you should drag your teeth along the inside of your cheeks.
Check to make sure that you cannot easily slide your finger into the helmet along the side of your temple.
Hold the helmet with one hand on each side. Without moving your head, try to move the helmet up and down, and side to side. You should feel the skin of your head and face being pulled as you try to move the helmet. If you can move the helmet around easily, it is too big. Try a smaller size. Please note that during this check, the chinstraps should be properly fastened.
