Advanced Protection
The One K Defender Convertible features an injection-moulded outer shell constructed from polycarbonate and advanced ABS composite, combined with a high-quality EPS liner.
The EPS liner is designed to absorb and dissipate energy during an impact, with One K using carefully selected EPS density to provide effective impact absorption without compromising comfort.

Returns on Riding Hats
We are happy to accept returns on riding hats and helmets provided they are returned in unused, unworn, perfect resaleable condition, with all original tags and packaging intact.
As these are safety-critical products, we apply strict return standards to ensure every helmet we sell remains safe and compliant. Returns that do not meet these requirements will be refused and returned to you at your expense.
How to Package Your Return
- Always place the helmet inside its original manufacturer's box, where supplied.
- The manufacturer's box must then be placed inside a sturdy outer shipping box with adequate protective packaging (packing peanuts / bubble wrap).
- Use the original packing materials supplied with your order wherever possible.
- If your helmet was not supplied in a manufacturer's box, please return it using the same protective packaging it arrived in.
- Never return a helmet in just a mailing bag or in its manufacturer's box without an outer box.
- Ensure the outer box is large enough to protect the helmet from damage during transit.
Please do not attach tape, labels or postage directly to the helmet or manufacturer's box. Doing so makes the product unsuitable for resale and will incur a non-refundable 15% repackaging charge to cover the cost of replacing the branded packaging.
Returns We Cannot Accept
- Helmets returned in mailing bags.
- Helmets returned without an outer protective box.
- Helmets returned in damaged or undersized packaging.
- Helmets showing signs of use, damage or missing tags.
Any return that does not meet these requirements will be refused and returned to you. If return postage is not paid within 30 days, the helmet will be disposed of.
If you are unsure how to package your helmet correctly, please contact our customer service team before sending your return. We're always happy to help.
