Why We Love This

Backed by Science the Trauma Void Lynx is equipped with Multi-Directional Impact Protection System or MIPS. The combination of the well-venilated helmet and the Coolmax liner helps to wick away moisture, keeping your head comfortable. This deeper profile helmet has a dial-fit system, making it easy to fit a variety of head shapes and sizes.

How are our riding helmets tested?
Our riding helmets are tested in two versions; one with and one without Mips. To be approved, helmets need to reduce rotational forces by at least 10%. In most cases, our helmets significantly exceed this limit. Helmets are impact tested on the forehead, from the side, from the top, and the side from the front. The tests take place on all models and sizes, and are documented both via sensors and high-speed cameras. Back on Track Helmets have won numerous BEST IN TEST AWARDS.
  • ASTM/SEI certification
  • MIPS technology inside 
  • Removable and washable CoolMax lining
  • Comfortable design with great ventilation
  • Smooth outer shell that is easy to clean
  • Screen and chinstraps made of durable PU leather
  • Dial-Fit System
  • SEI/ASTM F1163.15

Key Specifications
  • MIPS: Yes
  • ASTM/SEI: Yes
  • Round : Yes
(Maintenance Dose = )
Ingredient Amount
To measure for the best fit, find the circumference of the head. To begin, use a flexible tape measure and place it 1-1/2 cm above the eyebrows, skimming the tops of the ears, take it around the back of the head to the fullest part. Using the rider’s measurement and the chart below, find the corresponding helmet for their size range.  Please note that the rider’s hair should be as worn when using the helmet.

The Lynx helmets include a dial-fit system, after fitting the rider for their helmet, adjust the dial so that the helmet fits securely, then adjust the chinstrap.

Sizing Chart for Trauma Void Lynx Smooth Helmet
Round Yes
Trauma Void Lynx Smooth Helmet is rated 4.6 out of 5 by 68.
Rated 5 out of 5 by from Had a fall in this helmet and bought it again! Beautiful and safe. Fits snug! Saved my noggin! I do not have one bad thing to say about this helmet. A helmet that is rated super safe, but also has the look of the higher priced helmets! When I had a fall, I bought the same exact helmet again!

Rated 5 out of 5 by from This helmet saved my life I recently had the worst fall of my riding career and I really believe if I didn't have this helmet on I'd be dead- instead I walked away with a minor concussion and some non head related injuries. I love this helmet it's comfortable and I love that even though it is adjustable it still fits your head properly. I will be purchasing another one to replace the crash helmet. I will never ride in any other helmet.

Rated 5 out of 5 by from only used it a couple of times, but it is exactly what I wanted. I broke another helmet due to fall off horse a couple of months ago. THAT helmet was very inferior to the Lynx; I might NOT have suffered a concussion if I was wearing the Lynx!

Rated 5 out of 5 by from Fall tested worked great! I bought this helmet because I was worried about rotational falls on the one horse I ride. Well I was lucky I had this on the other day at a show. I got to jump a horse I had never rode before and he deer jumped over the jump and I landed really hard on my head. People up in the barns heard me hit. The helmet is pretty banged up but I only walked a way with slight headache. I will never buy another helmet again. Great helmet especially for the price

Rated 3 out of 5 by from Still torn. I really want to like this helmet. I like the shape and think it looks great. It feels a bit bulky on my head. The thing that I am really struggling with is the turn dial on the back of the helmet. Oddly enough, that was why I picked this helmet. It turn dial is high in the helmet, it doesn't stick out, but because of this, it is difficult to get my fingers on it to turn it. It is also very sleek, which makes it look good, but makes it hard for my fingers to stay on it while trying to tighten or loosen it.

Rated 3 out of 5 by from Great fitting helmet but can be hot This is a great helmet, fairly attractive, and at a great price point.... BUT, it lacks a lot of ventilation. I noticed as the weather has become warmer, I’ve been super flush and my face has been sweaty, when it’s barely 70 degrees. After talking to others, it’s not just me. Upside was I was warm all winter, but shopping for a better ventilated helmet for summer! I was previously wearing a long oval OneK for fit reference.

Rated 5 out of 5 by from Great helmet, great price I was due for a new helmet after my latest one aged out after a few years. I have been eyeing helmets with MIPS for a while and was happy go find this one for such an affordable price. The sizing seems to run a little small, I measured 58 centimeters but the medium was too small so I sized up to a large. The dial fit is great and allows me to customize the fit depending on how I wear my hair. I have not fallen off with this helmet but feel confident in the added protection the MIPS layer offers.

Rated 5 out of 5 by from Great protection and good looking I bought this for my daughter it looks exactly like the more expensive helmets but provides better protection.
Date published: 2021-01-29
Rated 4 out of 5 by from Runs small I bought this in a Med and wore it around the house for awhile. It was really hot, bulky, and tight and didn't have much ventilation in a 70 degree house. But for a competition instead of all day trail rides, it would be fine. I tried to exchange it for a larger size and they were out.
Date published: 2020-12-23
Rated 5 out of 5 by from Great fit I bought this helmet a month or two ago because I wanted to upgrade to the MIPS system after doing some research. Luckily I haven't tested it yet but from a fit point of view, it's very comfortable and lightweight while also feeling protective and secure. The adjustability feature is great because it allows me to wear a balaclava when it's cold or put my hair up or down.
