    Frequently Asked Questions

    Q: What are the design improvements in the new 2024 Advantage H2 and Pro3 vests which came out in November 2023?

    A: The new vests have a three-layer construction and extra shock absorbing pads have been added to the inside of the vests (front on Pro 3 and both front and back on Advantage). This extra shock absorbing padding results in the new vests fitting smaller than the the original models. I think this was one reason that Hit Air added a size option with the new medium/large option for the Advantage. The vest has also been certified to the newest rigorous European safety standard (certified using the new all-in-one English bungee with intergrated English saddle strap). *all lanyards are still available and interchangeable

    Q: How should I attach the lanyard to my saddle?

    A: If you are using an English saddle, you can choose the new all-in-one bungee lanyard with integrated English saddle strap. We still offer the original Hit Air Engish saddle strap that is used with the Hit Air bungee lanyard. Western riders should use a night latch or strong nylon dog collar, which you insert through the loop in the lanyard and then buckle securely around your pommel. If you have an endurance saddle without a hole under the pommel, then you may be able to use our Amish saddle strap which can be attached to secure rings on your saddle. We do not recommend attaching to a saddle horn (may be pulled off of horn depending on trajectory of fall), using a carabiner or decorative saddle ring, or wrapping lanyard around the pommel (may cause lanyard to be too short). See more detail by clicking on our Bungee Lanyard and Night Latch located under Accessories.

    Q: If a rider forgets to release the lanyard (bungee lanyard or coiled wire) when dismounting the horse, will the airbag activate? What is the activation distance?

    A: Quite a strong pulling force (66 to 77 lbs) is required to activate the airbag. We recommend that a rider should weigh at least 100 pounds when using an adult vest, or 55 pounds for the kids vest. When dismounting, the rider may feel a strong tug and realize that he/she has forgotten to disconnect the one-touch release. However, be careful not to dismount a horse forcibly to avoid unnecessary activation. Always disconnect the one-touch connector before dismounting a horse. The vest will deploy when the activation distance is reached. This activation distance is dependent on the fully extended length of the lanyard, which can vary depending on model and the adjustment of the lanyard length. The length of the motorcycle or horse lanyard is all based on the user adjustment. If you want a faster deployment time, then the rider should shorten the lanyard to make the key ball pull out sooner into a fall or dismount.

    Q: What are the differences between vest models?

    A: The Advantage H2 and Advantage Max focus more on hip coverage, since these models have two smaller telescoping hip airbags, providing wider hip coverage, that deploy instead of a single larger and longer rear drop down airbag on the Pro 3 and Pro Max. All of the vests except for the Original LV and SV2 have added padding behind the cartridge to minimize sound. The Advantage has the quickest (.09 sec) gas release mechanism and has an adjustable belt near the bottom buckle; the PRO and MLV also have an agjustable lower belt which can be adjusted on both sides. Both the Advantage Max and Pro Max add a built-in back pad and formed zippered cover for the cartridge. The PRO (MLV3), PRO Max and MLV models have the largest rib airbag and rear drop down bag, and have adjustable belts on both sides near the bottom buckle. The MLV reflective models are designed for both motorcycle and equestrian riders; there is a longer coiled wire that is standard for the motorcycle. The MLV-YC is a highly visible yellow flourescent color and has fully reflective Lumidex material and also comes standard with motorcycle coiled wire. The LV and SV2 models were the original models that are being replaced later in 3034 and have the smallest rear drop-down airbag. The smaller 48cc cartridge and older inferior style keybox for the LV and SV2 are located behind the airbag next to the rider's body unlike all other newer models, where the airbag is behind the keybox. The LV and smaller SV2 are often seen on eventers and jumpers, who wear these over the hard vests.

    Q: If an airbag is activated and inflated, can it be reused?

    A: Yes, it can be reused over and over again provided it has not been damaged. Simply replace the gas cartridge using the tool-kit that came with the vest. See inspection and servicing option category on this website for recommendations.

    How to replace a cartridge in the H-Model/Advantage

    Q: If an inflated airbag is damaged by friction with the road surface in an accident, will it still be effective?
    A: Yes, in fact the job of the airbag will already have been done - that is it will have dissipated the shock well before it is torn or damaged. If you are concerned that the vest has been compromised after the accident, see the Vest Inspection and Servicing option on this website.
    Q: How long will the gas cartridge last?
    A: Indefinitely, but it should be replaced if the surface shows any signs of deterioration or rust. (Of course, activated cartridges must be replaced.)
    Q: Can I use a vest with buckles on a saddle with a horn?
    A: Yes, but realize that it is possible to snag your buckle on the horn or scratch your saddle with the buckle, so unbuckle before dismounting. It is possible even to snag the zippered model Advantage or any article of clothing, so be careful to avoid snagging your vest. Also, we warn not to attach your lanyard/tether/coiled wire to the horn, since the lanyard could be pulled loose from the horn depending on the trajectory of the rider.
    Q: Can I wear a light backpack or something similar overtop an Hit-Air vest?
    A: Yes, but be careful that the straps or anything worn over the vest do not press against the airbag interfering with its ability to inflate freely. We generally recommend if wearing the vest with a coat that you wear the vest over the coat to insure that the vest inflation is not restricted. Optional Hit-Air buckle extenders permit expanding both the top and bottom vest buckles. We do wear a duster like the Muddy Creek rain coat over the vest, since there is plenty of room for expansion of the vest.
    Q: What maintenance is required for the Hit-Air vest?
    A: Hit-Air vests should be hung up in a temperature and humidity controlled space when not in use. You should avoid leaving your vest and CO2 Cartridges in extreme temperatures or exposing them to extreme temperature changes regularly. Do not leave them placed on or covered by any damp material such as saddle pads. The manufacturer now recommends that your vest be inspected annually (see vest inspection and servicing). If you are concerned that your Hit-Air vest is damaged and it is not over 5 years old, we can direct you to the authorized Hit-Air service provider/importer to inspect your vest and insure it is still functioning as intended. During inspection, your Hit-Air vest is checked for proper inflation and deflation and the outer material is checked for damage. If they encounter any issues with your vest, they will call you to discuss next steps for repair or replacement. Hit-Air recommends annual inspection and will not service a vest over 5 years old. They can perform minor repairs. The service provider will direct you to print out their downloadable service form, fill it out, and ship it to them with your vest. After inspection and servicing, they will ship it back to you within 5-7 business days after receiving the vest. Your vest is shipped back to you with a new CO2 cartridge. The cost for this service is currently $70 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. You can clean with a damp cloth, but do not put in washer or use harsh chemicals. Check the cartridge for rust or corrosion and replace if you see signs of corrosion. We had a customer bring her vest to our home, thinking the vest was damaged, since they could not deploy the vest. I attached a special attachment with a handle that we use to test deploy a vest and the vest was fine.
    Q: What is the purpose of the red plastic slide below the gas cartridge?
    A: The red plastic slide must always be in the up position to enable the vest to deploy; the red slide is not required for operation of the vest. You can optionally slide this red slide down over the key-ball when re-inserting the key-ball after a vest deployment. The red slide will only go down covering the key-ball if the key-ball has been correctly seated. If you use the red slide when reloading your vest after a deployment, you must insure that you slide the red slide back in the up position or the vest will not deploy. Also, do not replace the cartridge before you have re-inserted the key-ball mechanism.
    Q: How can I tell a used deployed gas cartridge from a new one?
    A: The used cartidge will have a hole in the seal at the bottom end of the cartridge.
    A: According to TSA's website, a life vest can be in carry on or checked luggage, however it is up to TSA discretion. It is important you tell TSA that it is a “life vest” as seen in their website link. We suggest you print the form, found on the TSA website, and bring it with your vest. The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.
