One K Defender

One K Defender is for riders with high demands on both safety and function. The helmets in the series are known for their solid construction, precise fit and thoughtful details that make a difference in everyday life.

With an outer shell in polycarbonate and ABS composite, efficient ventilation and a comfortable, adjustable chin strap system, the Defender series combines technical strength with a classic look. There's nothing superfluous - just well-chosen solutions that support you in the saddle.

At Unamari you'll find the classic model, the technical Defender Pro and the flexible Defender Convertible. All are built on the same basic principle: Protect, support and perform - every time.

One K Defender Pro - when every detail counts

One K Defender Pro is the helmet for you if you ride a lot and expect your gear to just work - every time. It's designed to be both robust and comfortable, with a snug fit and materials that stand up to daily use in the stable and long hours in the saddle.

It's a helmet made for riders who want to feel safe and comfortable, whether they're riding at home or at a competition.

Technology and safety in focus

The Defender Pro is built with a strong polycarbonate and ABS outer shell - providing great protection in case of an accident. With a soft and washable liner that wicks away sweat and feels comfortable against the skin, you can be sure to have a riding helmet you can use throughout the day without any problems. These are also available at Unamari.

Ventilation is positioned to let air in at the front, sides and back, making the helmet comfortable to wear - even during long rides. And if you choose a model with MIPS, you get extra security against the rotational movements that can occur during a fall.

One K Defender Convertible

One K Defender Convertible is perfect for the rider who wants to switch styles without compromising on function or safety. This helmet has the same great features as the rest of the Defender range, but with one key difference: you can change the top, front shield and frame whenever you want.

This allows you to match the helmet to your outfit, your race jacket or just your mood - without having to buy a whole new helmet. It's especially great for riders who want a combination of durable gear and personal style.

And of course, the Defender Convertible is also available in MIPS variants, so you get the same high level of protection and comfort you expect from a One K riding helmet
