Beautiful matte grey helmet with a glossy grey top and silver chrome front and frame.

The One K Defender is a lightweight yet robust riding helmet with a narrow visor, a strong
outer shell, excellent ventilation, and a fantastic fit, ensuring maximum comfort and
safety.
Safety first
One K riding helmets are made from an advanced injection-molded polycarbonate
and ABS composite outer shell, combined with an EPS inner layer. The EPS material is the
most important element responsible for impact absorption in helmets. One K uses
only the highest quality EPS with a density that ensures optimal shock absorption.
The helmets are, of course, VG01 certified.
Comfort
One K riding helmets are exceptionally well-ventilated thanks to two front vents,
two side vents, one rear vent, and two central ventilation channels. The helmets
have a comfortable, adjustable harness, synthetic suede lining, and a
Fast-Tex buckle.
One K helmets are available in three shell sizes, which, combined with removable
One K liners in sizes XS to XL, ensure a perfectly customized fit. The liner, which
is sold separately, is made of a washable, quick-drying material that also
regulates moisture and is antibacterial.
Design
One K helmets are the result of a perfect blend of advanced technology
and strong design. With modern features and a look that reflects timeless
equestrian aesthetics, One K combines the best of both worlds, whether
you prefer a glossy, matte, suede, or genuine Swarovski crystal-embellished finish.
The possibilities are endless.
Inner liners sold separately
The helmet meets the EN1384-2023 safety standard.
