If your Hit-Air vest is having any issues or you just want it inspected, our service provider's Inspection Department is here to help! Their team of knowledgeable in-house inspection staff is trained to test your vest and complete minor repairs. During inspection, your Hit-Air vest is checked for proper inflation and deflation and the outer material is checked for damage. If there are any issues with your vest, our service provider will call you to discuss next steps for repair or replacement. Inspection is not only for damaged vests! Our manufacturer recommends annual inspection for all Hit-Air vests. Annual inspection extends the life-span of your Hit-Air vest and ensures it is working properly so you know you are always protected. Please note, we are unable to service vests over 5 years old. If we receive a vest over 5 years old, the vest will be disassembled and disposed for safety. Customers who do not have a proof of purchase date document, please send an email to info@hitairsports.com with the model, size, and the 2 numbers and letter stamped on the bottom of the CO2 housing. To locate this information, unzip the cover around the CO2 cartridge. The model will be listed on the label on the inside of the cover and the 2 numbers and letter will be stamped in white at the hole for the setting bolt. The manufacturer recommends replacing key balls and lanyards when signs of wear appear. Any items purchased on the same order as an Annual Inspection will ship with vest after inspection is completed. If these items are needed sooner, please purchase them on a separate order. If your vest has visual damage, such as fabric damage, please email us pictures of the damage prior to purchasing Annual Inspection. Some repairs cannot be done in our US office and must be done by the manufacturer. After your purchase is completed, you will receive an order confirmation email with a link to a downloadable Annual Inspection form with shipping instructions. Please fill in the Annual Inspection Form and ship it with the vest and key ball. Do not ship lanyards and CO2s. During inspection, your vest will be tested for proper deployment, inflation, and deflation. The outer material will be inspected for any signs of damage. If any issues are found, we will contact you about next steps regarding your vest. If your vest has no issues during inspection, it will be sent right back to you with a new CO2 cartridge installed. Inspection typically takes 3-5 business days plus shipping transit time. Please ship all vests via FedEx or UPS. We are unable to receive USPS packages at our office. If you have to ship the vest by USPS, expect a possible 1-2 week delay in inspection to allow us time to pick up the package at the Post Office. Please be aware, we have had issues with USPS mishandling and losing packages, leading to further delays. Inspection fee includes return shipping cost. Your vest is shipped back to you with a new CO2 canister. The cost for this service is currently $90 plus shipping. You may also choose to test your vest by manually deploying your vest. Note that it requires at least 66 to 77 pounds of force to activate your vest, so it may require a strong person to quickly yank the lanyard with one hand while pressing against the vest with the other hand.
