First, measure the circumference of your head with a measuring tape.
Measure from the highest point of your forehead, just above your
eyebrows, horizontally backwards to the highest point of the back of
your head and around.
Based on the measurement, choose the size from the table below.
However, unlike hats, helmets cannot be sized by head circumference alone.
Also, helmets of the same manufacturer may feel different even if they
are the same size depending on the model.

The V4 helmet was created to exceed the standards required for the world's toughest sport. The "3-stage shock-absorbing system" combines a lightweight yet strong carbon shell with two layers of EPS liners of different hardness. In addition, the shell and EPS liner are specially designed for each size to provide a more premium fit. Top riders such as Ken Roczen, Ryan Dungey, Chad Reed, Ivan Tedesco and many others have used this product, proving it's dependability and racing performance. FOX has put everything into the development of this helmet, which is above the premium level in terms of quality and performance.
[Function] 1. equipped with MIPS (Multi-Directional Impact Protection System) 2. carbon fiber shell 3. 4 sizes available for both shell and EPS liner to provide a good fit 4. cheek pads designed with a longer mandible line for better fit and hold 5. EPS liner combining two different density materials for superior shock absorption 6. interior using high-tech material "Dry Lex" to keep the inside of the helmet comfortable 7. 15 air intakes and 8 exhaust vents efficiently dissipate heat and vapor during riding 8. for racing use only (Snell 2010 standard, DOT compliant, MFJ approved)
What is MIPS (Multi-Directional Impact Protection System) ?
MIPS acts as a protective fluid for the brainMIPS' unique head protection system was inspired by the developer's attention to the structure of the human brain. The brain is surrounded by a low-friction buffer fluid called cerebrospinal fluid. MIPS absorbs the impact to the head in the event of a fall by placing a low-friction liner that performs the same function as this protective fluid between the EPS liner and the comfort liner of the helmet. The synergistic effect of the protective function of the brain itself and the protective function of MIPS provides maximum protection of the head. Experiments have proven that the use of MIPS reduces rotational acceleration by 20-35%, which mitigates the impact of a fall and reduces the pressure on the brain.
There is no such thing as an ideal fallUsually, the strength test of the helmet is done by dropping it vertically on the hard ground. In reality, however, the force of impact is often applied diagonally, rather than vertically during a fall. The large rotational energy created and the damage to the head can cause severe brain damage. MIPS is a revolutionary system that was developed by researchers with an eye on such "reality" and with the aim of reducing the number of injuries that occur in actual falls. In fact, experimental data show that there is a significant difference in the absorption of rotational energy between helmets equipped with MIPS and those without MIPS. Of course, even for vertical impacts, it has the same level of absorption as conventional helmets. MIPS offers a much higher level of protection and peace of mind than conventional helmets.
