What is a One K Liner?

A One K Liner is the removable and replaceable liner that sits in your One K riding helmet and makes sure the helmet feels comfortable, fits correctly and stays fresh. The liner is made of a soft, moisture-wicking and antibacterial material that effectively wicks sweat away from the skin for a dry and comfortable experience.

The beauty of a One K Liner is that it can be removed and washed, making it easy to keep your helmet hygienic and smelling great. At the same time, you can easily replace the liner if it gets worn out or if you need to adjust the size or shape of the helmet.

At Unamari you'll find a wide range of liners for both everyday and winter use - so you can make sure your helmet always feels like new and fits you perfectly.

Liners for all One K riding helmets

No matter what model you ride with - whether it's One K Defender, Avancé, Convertible, Xtreme or a model with MIPS - you can find a liner for One K that fits your helmet perfectly. All One K helmets are designed with a smart interchangeable liner system, so you can easily replace the inside without tools.

This means you can always get your riding helmet to fit perfectly just by having the right liner. This is especially useful for growing children and youth or if multiple riders share the same helmet. The liner also ensures that the helmet fits correctly and stably - an important factor for both comfort and safety.

Types of One K Liners

There are several different types of One K Liners, so you can find exactly the version that fits your head shape, the season and the helmet model you use.

One K Normal liner

The classic One K liner has a round fit and fits riders with a regular head shape. It's easy to fit, fits snugly and is made from a soft, moisture-wicking material that can be removed and washed. Perfect for those who want a simple and comfortable solution in their daily riding helmet.

One K Oval liner

If you find that your helmet presses at the sides or feels loose at the front and back, an oval liner may be the solution. It's shaped for riders with a more elongated head shape and ensures a better distribution of pressure in the helmet. The result is a more stable and comfortable fit that also improves safety.

One K winter liner

A One K winter liner is lined and provides extra warmth on cold days. You can choose between two versions: one with ear coverage to keep your head and ears warm, and one without if you prefer a little more air around your ears. Both versions are ideal for winter riding, where comfort is easily compromised without the right liner inside the riding helmet.

One K MIPS liner

If you have a helmet with MIPS technology, you need a special One K MIPS liner. This variant is designed to work in conjunction with the internal MIPS system and ensures that the protective properties of the helmet are maintained. It is available in several sizes and fits, and the material is the same soft and sweat-wicking as the standard liner.

One K sunglasses

One K sunglasses are a smart and practical accessory that can be integrated directly into your One K riding helmet. Specially developed to match the helmet design, they provide effective protection against sun, wind and dust while riding.

The sunglasses can be easily mounted and slid up and down as needed, making them ideal for both daily riding and competitions. They come in different shades and can be combined with both regular and MIPS helmets from One K.

It's a functional solution for riders who want better visibility in bright light - without having to use separate sunglasses that can interfere with helmet placement or create pressure on the face.
