Defender Chrome Stripe Helmet

One K


The One K Defender Chrome Stripe Helmet combines a classic design and cutting edge impact technology to help keep your head safe while riding. This helmet is made with a Polycarbonate and Advanced ABS Composite shell with injection molded shell design to provide a high standard of impact protection and help shield the head during falls. 

The inside of the helmet is made of a removable, moisture-wicking, and anti-microbial lining that can easily be switched out and washed as needed. Stainless steel mesh and center stripe vents help keep your head cool during hot weather riding. Can be used for everyday use at home but attractive enough for the show ring. These helmets are available in round and can be special ordered in oval.

Super comfortable!


I love this helmet! Its super comfy and is very well ventilated. One of my favorite features is being able to wash the liner, it makes the helmet fresh again.
