H&H Sports Protection is recalling 4,218 VCAN V531 motorcycle helmets in sizes XS, S, M, L, XL, and XXL, sold exclusively through Amazon.
The helmet retention system may fail, allowing the helmet to separate from the wearer's head in a crash.
A helmet that doesn't stay secured to the head can increase the risk of injury.
What to do
Amazon will notify the helmet purchasers and instruct them to return the helmets for a full refund.
The recall is expected to begin in November 2019.
Owners may contact H&H Sports at (626) 444-0107.
