Why We Love This

The Hit Air Advantage Vest is a culmination of more than a decade of experience in airbag technology by MUGEN DENKO, LTD. The Hit Air Airbag Vest is a "harness type" airbag that employs the new higher speed key ball mechanism which activates the CO2 cartridge.  Versatile design makes it perfect for riders of all equestrian disciplines including Eventing and Western. Imported.

This vest is designed for adults, and to deploy properly the rider must weigh a minimum of 100lbs. If a rider is under 100lbs, please contact our Customer Care Team – we would be happy to help select the right vest!

Please Note: Our Regular Length Adjustable Bungee and Clip Bungee Lanyards are recommended for customers with horses 15.2 hands or taller. If a customer will be riding horses between 13.2 hands and 15.2 hands, we recommend a Short Length Lanyard. Air vests should NOT be used on horses under 13.2 hands.

Includes: Instruction Booklet, Canister-Changing Tool, (1) Canister, (1) Saddle Strap, & (1) Clip Bungee Lanyard 

Western Lanyard is available to be purchased separately. Click Here!

CAUTION: Safety equipment must fit properly and be appropriately secured with manufacture approved parts only. Altering or adding to safety equipment voids warranty and can result in injury. As a safety precaution, inspect all products prior to each use.

  • Top fast: 0.09 sec deployment time!
  • Attention to detail is unmatched by any other brand of airbag apparel
  • The neck airbag is significantly larger than the leading competitor's
  • The neck airbag inflates first, where most injuries occur, followed by (in only fraction of a millisecond) the torso and hip airbag
  • The key box where the CO2 cartridge is deployed is protected from dust and dirt and provides sound insulation to minimize spooking the horse during an unintended deployment
  • Added comfort in the saddle because the hip air bags are concealed inside a special pocket making it unnecessary to have a long "duck tailed" style that can be uncomfortable in the saddle
  • Cool to wear due to the open design
  • Cartridges:  S and M uses 50cc

Hit Air® Advantage Airbag Vest is rated 4.6 out of 5 by 50.
Rated 5 out of 5 by from Smart Safety Investment! Due to an involuntary dismount, I decided it was time to purchase an airbag vest for my daughter. Luckily, she wasn’t injured. I was looking for a safety vest that she could not only ride in every day but could show in as well. After lots of investigation, I decided the perfect vest was the Hit Air® Advantage Airbag Vest. It’s light and is not noticeable when worn over her riding jacket. The Hit Air® Advantage Airbag Vest is very lightweight, easily fits over all outerwear, and is comfortable. I was worried about the possibility of accidentally discharging the airbags. She has taken numerous rides and has always remembered to disconnect before dismounting. I even measured to see if the tether was long enough and as it claims, there is a slight tug if you ever forgot to disconnect it. She rides several horses a day, so the vest adds to my confidence, as a mom, that she is protected. I only wish I had purchased one earlier. Now, I am purchasing the Hit Air® Advantage Airbag Vest for myself. I ride Western and am older. I feel it will boost my confidence. I am sure my horse will appreciate that! I'm telling all my horse friends since they all wear helmets, this is no less uncomfortable or inconvenient, and it’s a smart investment!

Rated 3 out of 5 by from not my favorite Definitely worth the money safety wise but I found it quite uncomfortable. This is a very protective vest but it was very rough and uncomfortable around my neck and it is super baggy (which I know it is made to be like this) and annoying to wear. If you can, definitely try one of the soft shell styles. Smartpak was great and gave me my money fully back and put it towards a free jump vest. HIGHLY RECOMMEND THE FREE JUMP!

Rated 5 out of 5 by from Light weight and great protection! I wanted to write this review when I first got the vest because I loved how light weight it was and comfortable. But, I waited because I wanted to be able to add part to my review in case I ever fell off. Well, I fell off today and let me just say this is the best money you will ever spend. I ride a 4 year old and knew it was going to happen. He was a jerk and went left when he knew he was suppose to go straight. I got off balance and he tossed his head causing me to fall off. It was a slow fall where I had enough time to want to try and unhook my vest so it wouldn’t inflate. But I didn’t reach it in time and glad I didn’t. The vest inflated mid fall. It was fast and not that loud. My horse did spook a touch more when he heard the pop, but just more of a scoot away from me. This vest inflates so well that I felt let a sumo wrestler. I was so happy with all the coverage. The best was the coverage around my neck. I felt so protected. I know have to learn how to put my bags back in and put a new cartridge in, but again, so worth it. I can’t say it enough, buy this vest. You will ride with more confidence knowing you are protected.

Rated 4 out of 5 by from Size up if on the upper limit of height range This is overall a great vest. The instructions for reassembly and care are easy to understand and follow, it's very comfortable, and it seems to be high quality and durable. The only thing negative I have to say is that if you are on the upper limit of the height range, I recommend sizing up. I'm 5'4" and slender so I purchased the small size. Seemed to fit great when I tried it on. However, I accidentally deployed the vest after my first use because I forgot to detach the pull cord from my saddle when dismounting. The vest functioned perfectly and completely deployed before my feet hit the ground. It was impressively quiet too and didn't spook my horse. All great things. But I noticed that when fully inflated the bottom air bags did not cover my hip bones (the bottom of the vest rested just above), which was an advertised feature of the vest that persuaded me into purchasing this one. Unfortunately I can not return the vest now that it has been used for a larger size, so I will make do, but had I known I would have sized up. Everything else about this vest is awesome, but I recommend getting a medium if you are 5'3" or taller and want hip bone coverage.

Rated 5 out of 5 by from Will not ride without this! I bought this vest after coming off my 4 year-old green mare who spooked and bolted in the arena and when I came off I hit the railing pretty hard. Took me about a month to recover. I'm pretty sure I bruised some ribs and was black and blue for quite a while. I quickly realized that I needed some protection and bought this vest after reading the reviews. Had the chance to test this vest after my mare spooked the other day when she saw my friend's horse spook at a a woman standing on a picnic table gesturing wildly with her arms to get her horse in the arena to run. I lost my balance and came off and landed on my back on the hard rocky ground. Vest inflated perfectly and I didn't feel a thing! It felt like I landed on pillows! My left hip was pretty bruised but had I not had that vest on I'm pretty sure I would have broken something on that hard ground. I will never ride without it again! It's just not worth it. Saved me a trip to the hospital.

Rated 5 out of 5 by from The COOLEST Vest I've found I've been wearing this as my "summer" vest as other vests have been just too the Helite but it's like wearing a plastic bag in the summer heat (I do wear in cooler months tho-- love the look of the gilet...and the newer 2.0 version does look cooler than mine) and I had to find an alternative. Didn't have as much confidence in this brand as Helite -- the goofy "air-bag" graphics etc-- but had a pretty solid fall 2 months ago and can attest that while my arm ended up broken, I got up and walked away= the Hit Air took the majority of the impact and did its job. Only thing is, I think the plastic buckles nailed me pretty hard in the chest (as opposed to the Helite and other zipper models), BUT a minor problem overall...back neck torso protected. Just ordered the optional chest pads that you can velcro into this vest, hopefully that will do the trick. Will continue to ride and show in the Hit Air.

Rated 5 out of 5 by from Tried and Tested (twice!) I have now successfully tested this air vest twice over the course of the past 2 years - once on a x-country course and once jumping in an indoor. Both were high impact falls from my 17.1 warmblood, and both times this vest saved my neck - literally! You might be thinking twice about the high price, but it's saved me a couple of trips to the emergency room, which would have been much worse.

Rated 5 out of 5 by from Amazing vest, poor support from SmartPak I love this vest. I've had mine for three years now. It is light, breathable, and adjusts around bulky winter clothing. Unfortunately, SmartPak does not carry any of the accessories and I've ended up purchasing them through other vendors.

Rated 5 out of 5 by from Worth every penny and more I currently have an eight-year old green mare in training, and I decided that having one of these vests would not be a bad idea (I'm not as fearless as I used to be in the saddle). Today was a seemingly normal day in the saddle until a dog came around the corner of the barn and caused my horse to spook. She bolted and I lost my seat and the reins. As she cantered around the corner of the arena, I fell into the arena fencing. I literally felt no pain in my neck, back, or chest as I hit fence and landed in the dirt. In the past, my neck always gets jerked around during a fall, but the Hit Air vest prevented that completely. This is worth every penny and more!

Rated 5 out of 5 by from It Works! I "tried" this vest in an open air arena a couple of weeks ago. My 19 yo lease TB spooked and my whip in hand brushed him. He bolted a bit, I flew threw the air over a low dressage rail and landed about 6 feet away. The landing was on my back none the worse for the fall. He's about 16' 3 and I'm 5' 4" --- we were trotting at the time. Some folks, I guess, worry about what it says about them to wear a vest on any horse --- let alone a good guy. I just worry about being able to do what I enjoy as often and as long as I can. 2 hours after this fall I went for a couple mile run and the next day was back up on my horse. Pro Tip: The manual that comes with the vest explains how to "set the strap" length so it does go off. Make sure you read and follow those directions. It is possible to dismount and have it not go off. I did this before my fall and was surprised. The day of my fall I set the strap length, whew, good move. I'm sure it would have deployed given the distance I went but still....
