One K Helmets Size, Fit, and Style Guide

Michelle Drum

Equestrians will tell you there is no more rewarding sport than horseback riding. And while that’s true for many, it is also one of the more dangerous sports. Horse riding may get less attention from a safety perspective than football and soccer, but there are numerous risks of riding horses, including the risk of head injury. Investing in a good quality helmet that meets or exceeds established safety standards is essential for keeping riders safe. One of the leaders in quality riding helmets is One K Helmets. In this guide, we’ll share what you need to know about their helmets and why we love them (and think you will, too!).

About One K Helmets

When you purchase a One K helmet, you’re choosing a company that’s invested in the perfect synergy between function, comfort, and fashion. This is a company that understands the unique needs for equestrian helmets and balances the need for safety with advanced technology, without compromising on rider comfort or quality. The result is an aesthetically-pleasing helmet that riders in all English riding disciplines will love, including dressage, hunters, jumpers, eventing, and equitation. 

One K helmets exceed safety standards in all tests, including impact, side distortion, and penetration. All helmets are made from the highest quality materials, including a polycarbonate and ABS composite injection-molded outer shell with an EPS liner for maximum impact absorption. They also have a number of comfort features that come standard with all One K helmets, including a moisture-wicking, anti-microbial, and washable liner with an adjustable comfort padded harness.  

These helmets don’t skimp on ventilation, featuring two front, two side, one back, and two center stripe vents for optimal airflow. On top of the already stylish design, they also offer some incredible customizations for personal flair. One K helmets have a fantastic and well-earned reputation, and they even earned a spot on our list of the top five safest horse-riding helmets. They may be one of the newer kids on the block when it comes to helmets, but they are also among the best.

One K Helmet Sizes

One K helmets come in multiple shell sizes and two shapes. They offer a regular and a long oval, the latter of which has a slightly narrower side-to-side measurement and an elongated head from front to back. Use the One K foam liners to provide any adjustments you need for the perfect fit. It’s still important to size your helmet properly, but this foam liner makes a great fit even better. And this system easily accommodates young riders and the adjustments they will need as they grow. Instead of buying a whole new helmet, they can simply change the liner size. Note that the regular and long oval helmets do use the same liners, as the shape is determined by the helmet shell and not the liner.

One K Helmet Sizing Chart

The sizing charts include measurements to select a helmet size and guidance for selecting the right liner size. The extra-small, small, and medium helmets can all be adjusted to different sizes. So the extra-small can actually fit extra-small, small, or medium, depending on the liner size selected.
