Due to regulations for transport of dangerous goods by air (IATA) and road (ADR), consumers are not permitted to ship Tech-Air® products themselves for return or servicing. In the event of a return or service request you must therefore deliver the goods in person to one of our Tech-Air® Hubs. Please ensure you first contact our Customer Care team to receive confirmation of the correct Hub and approval before visiting.
Tech-Air® Hubs are currently available in select countries. Additional locations across Europe will be launched soon.
Please use the map below to find your closest Tech-Air® Hub.
By purchasing a Tech-Air® product on the Alpinestars website, you acknowledge and accept this return policy. If you still decide to ship your Tech-Air® product as a return, Alpinestars Spa will not be held responsible for the transit of such goods and will not accept them as returns. For this reason, no refund will be issued.
For any questions, feel free to contact our Customer Care team before making your purchase.
