Careful, Trackable Fulfillment

Shipping Policy

Information about order processing, shipping estimates, tracking, international charges, delivery problems and transit damage.

Last updated: September 22, 2026

Order Processing

Most in-stock orders are prepared within 1–3 business days after payment and security verification. Weekends, holidays, presale products, high-volume periods, address verification and exceptional events may extend processing time.

Processing time is separate from the carrier’s delivery time.

Shipping Charges and Delivery Estimates

Available methods, charges and estimated delivery windows are displayed at checkout when supported. Delivery estimates are not guarantees unless expressly identified as guaranteed.

Weather, customs inspections, transportation disruptions, remote-area service, public holidays and other circumstances outside our reasonable control may affect delivery.

Address Accuracy

Customers must provide an accurate recipient name, street address, unit number, city, state or region, postal code, country, email and telephone number. Contact us immediately if a correction is required.

Changes cannot be guaranteed after fulfillment begins. Reasonable reshipment expenses may apply when a parcel is returned because of an incorrect address, refusal or unsuccessful delivery caused by customer-provided information.

Tracking and Split Shipments

Tracking information is provided when available. Initial carrier scans may require additional time to appear. Products may ship separately because of availability, package dimensions, warehouse location or carrier requirements.

International Orders

International parcels may be inspected by customs and may incur import taxes, duties, brokerage or handling charges. Unless checkout expressly states otherwise, these charges are the recipient’s responsibility.

Customers are responsible for confirming that a helmet may lawfully be imported and used in the destination market.

Damaged or Incorrect Deliveries

Inspect the parcel and helmet promptly. If a helmet arrives damaged, incorrect, incomplete or potentially compromised, do not use it. Contact us within 7 days of delivery with the order number and photographs of the outer box, shipping label, internal packaging and product. Keep all packaging until the case is resolved.

Missing and Delayed Packages

Before reporting a delivered-but-missing parcel, check the delivery area, household members, building management and carrier notices. Carrier investigations may require recipient confirmation and additional processing time.

If we cannot ship within the promised period, or within the period required by applicable law where no specific date was promised, we will provide an appropriate delay notice and cancellation or refund option where required.
