One K Helmets


One K helmets are very safe and also have an amazing design. There are so many different possibilities, that there is always a design that you’ll absolutely love. You could choose a simple design or you could choose everything a helmet could possibly offer. One K has the best of both worlds. You can choose a very chic and simple color of the top or you can go with a beautiful glitter front.

One K helmets boast the perfect synergy between advanced technology and aesthetically pleasing design. The One K helmets are composed of a Polycarbonate and advance ABS composite injection molded outer shell combined with an EPS liner. The EPS liner is the main part of impact absorption in a helmet. One K only uses EPS of high quality with a density that makes the helmets perfect for impact absorption.


One K helmets have a comfortably padded harness with a synthetic suede lining, a hook and loop adjustment, and a fast-tex buckle providing maximum comfort and an optimal fit.

The One K liner consists of a washable quick-dry fabric; it is moisture-wicking and anti-microbial. The removable liner provides a high level of hygiene. The One K helmet also provides a very high level of ventilation, featuring two front ventilation, two side ventilation, one back ventilation, and two center stripe ventilations. This combination of vents and materials creates optimal airflow in the helmet.

The helmet is very safe because of the MIPS layer. The MIPS’ added protection system reduces the rotational motion when implemented in a helmet by absorbing and redirecting energies and forces otherwise transmitted to the brain.


The One K helmets are available in 3 shell sizes. By using the One K foam liner you can achieve the perfect fit. This system allows the helmet to grow with a young rider. One K helmets are available in 2 shapes: Regular and Long Oval which emphasizes an elongated head from front to back and a slightly narrower measurement from side –to – side. Wearing a wrongly shaped or sized helmet can lead to increased pressure and discomfort. One K has plenty of options for the perfect fit. Please note that both Regular and Long Oval shaped helmets use the same liners. Shape is determined by the shell, not by the liner. To find the right size and fit for you, have a look at our helmets size guide.
