Regular price £150.00
Shipping calculated at checkout.

The Hedkayse|ONE Network helmet was designed by Wirral-based Jo. The design is inspired by sights encountered on the National Cycle Network ‒ urban and rural: road markings, planted gardens, rock formations, rolling fields, sand dunes and more. Random ‘bird’s-eye views’ and abstract grids are spliced together to form a vibrant, graphic representation of the Network.

The Hedkayse|One helmet is the world's first true multi-impact cycle helmet that provides unparalleled protection. Each helmet comes with a comprehensive 5-year guarantee.

For every purchase of a Hedkayse helmet through the Sustrans shop, Hedkayse are donating £50 towards our charitable mission of making walking and cycling easier for everyone.

What is Enkayse™? Why is it better?
Enkayse™ has been designed and engineered specifically to provide the same levels of protection as traditional cycle helmets, however the protection is repeatable. So, after everyday knocks and even larger impacts, the helmet recovers. The Enkayse™ liner has made Hedkayse | ONE the world's first truly multiple impact cycle helmet. 
Although the helmet is described as multi-impact, I'm still concerned about the safety. 
Hedkayse have conducted detailed studies under lab conditions to simulate over 100 high speed impacts (replicating crashes) and the performance of the Hedkayse | ONE is still above the EN1078 expected standard. For a more in-depth look at helmet safety and how Hedkayse performs compared to other helmets, have a read of the 'Making Sense of Cycle Helmets' publication, available to download for free here.

Is it suitable for other sports? 
The Hedkayse | ONE is designed specifically for cycling, but EN1078 also certifies it for skateboards and roller-skates. Other activities require additional legal certification.
Can children wear the Hedkayse | ONE? 
If their head measures at least 49cm. As written in the information on the helmet, it is advised that children do not wear the helmet while climbing or doing other activities where there could be a risk of hanging or strangulation. 
What size does it compress to? 
In its unfolded state the Hedkayse | ONE measures 21 x 30 x 14cm (width, length height). When folded it measures 11 x 36 x 14cm. That's a reduction in width by 1/2!
Is it Waterproof? Can I wash it? How do I clean it? 
The Hedkayse | ONE is designed to resist extremely wet weather and extremes of temperature; so, everything you will need for cycling! The helmet is made with built in anti-bacterial agents, however every-day life can be unforgiving! Hedkayse recommend warm soapy water to clean off markings, mud, sweat, and other stuff.
Is the Hedkayse | ONE well ventilated for hot countries? 
Anything on your head will increase the temperature, we have designed the helmet with 4 large vents running the whole length of the helmet to maximise ventilation.
Will my Hedkayse | ONE colour fade or change?                              Over time, yes. The "TAF" outer shell is designed to be incredibly tough and resistant to impacts. Exposure to UV light does cause colours to fade or change slightly over time. This is normal and most importantly does not affect the helmets physical properties or safety performance.
If I think my Hedkayse | ONE is faulty, who do I speak to?                We want you to have a perfect cycle helmet. If something goes wrong or you are concerned about a part of the helmet, please let us know. Send us a photo with your message to info@hedkayse.com, and we will work out what to do.
