How We Can Help

  • Helmet model, intended-use, feature and sizing questions
  • Order confirmation, address correction, cancellation or payment questions
  • Tracking, delivery, missing package or carrier concerns
  • Incorrect, incomplete, damaged or potentially defective products
  • Return, exchange, refund or warranty assistance
  • Safety, compliance or product-quality reports
  • Privacy requests and website-access questions

Information to Include

For faster assistance, provide your full name, order number, email used at checkout, product name, size, color, and a clear description of the question or problem. Include relevant photographs or video when reporting damage, defects, missing parts or incorrect products.

For sizing questions, include your head circumference measured according to the product size guide and identify the exact helmet model. Customer support can explain published sizing information but cannot guarantee fit without an appropriate physical assessment.

Never send a full payment-card number, card security code, account password or one-time verification code by email.

Safety Priority

Urgent Product Concerns

If a helmet appears damaged, has been involved in an impact, or shows a possible shell, liner, strap, buckle or retention-system problem, stop using it immediately. Contact us with the order number, photographs and a factual description of what occurred. For an immediate emergency, contact local emergency services first.

Response Expectations

Messages are reviewed in the order received, with active-order and safety-related concerns prioritized where reasonably possible. Shipping investigations, payment reviews, warranty evaluations and technical questions may require additional information or coordination with service providers.

Please avoid submitting multiple messages about the same case. Keeping communication in one email thread helps us review the complete history and respond more efficiently.
