A Simple trigger with 3 important features

1. The area that activates the inflation chamber looks like a pocket to conceal and protect the inflation hardware.
   
2. The pocket flap is secured with velcro to protect the inflation hardware from entanglement with lines, netting, brambles, or anything else that could cause the garment to inflate when not needed
   .
3. The pocket flap is the simple-to-use trigger. When you pull downward on the pocket, you detach the velcro-secured flap and activate the mechanism that inflates the buoyancy chamber. This movement is easy for even a gloved or groping hand.
   

Inside each inflatable garment is a high-performance buoyancy cell. It is made from the same material as inflatable lifevests used by the military-a tough 200 denier nylon coated with urethane to make it 100% air-holding. Fully inflated the air chamber will provide 16 kg’s of positive buoyancy.

What does 16 kg. of buoyancy mean?

An average 90 kg adult with deflated lungs weighs less than 4.5 kg’s in water. It works like this..

A 90kg person is approx 80% water. = 72.72 kg’s (water has no weight in water)

A 90kg person is approx 15% fat = 13.63 kg’s (fat is lighter than water)

Therefore the actual weight of a 90kg person minus 72.72 kg’s water and 13.63 kg’s fat = 3.65 kg’s

If this same person was to take a deep breath, inflate his/her lungs, they would probably float, and weigh nothing at all.

It is a good idea to put that one good lung full of air into your Stormy Seas garment and leave it there. Then, should the unexpected happen you will already have some positive buoyancy in reserve.
