Includes L airvest in black (adult), light pack and cartridge- leash sold separately. Worn 3 time- absolutely fantastic condition, just need a size smaller. This was set off accidentally during dismount once. All tubes were checked and everything was verified. When triggered, the airbag protects the neck, back, hips and spine. The 42-gram gas cartridge makes it one of the most gas-intensive airbags on the market. The Airbag is PPE (Personal Protective Equipment) and fits with any of the horse pilot line as well as this vest comes with the lite pack so can be worn alone on hot days! The ergonomic design and bi-directional stretch material of the waistcoat allow it to withstand airbag inflation while remaining lightweight. The mesh on the ribs and back provide the rider with breathability during intense effort. The cable that connects the rider to the saddle is magnetic, so you can connect or disconnect it with one hand, without letting go of the reins. The airbag has a flat inner pocket that keeps it close to the body. The cartridge is also flat. These two factors make the airbag one of the most discreet on the market. The rider can easily wear it under one of our compatible jackets: during competition with the Aerotech or Aeromesh and during training with the Teddy or Bombers.
