Furygan - Air Bag Sizes

WEARING AIRBAG SYSTEMS

A = Jacket width under armpits
B = Chest circumference with the equipment that will be worn when using the product (without the airbag waistcoat)

● Step 1 – Measure A
● Step 2 – Calculate 2 x  A
● Step 3 – Subtract B from the result of step 2 to obtain the measurement M

➜ If M is less than 13 then your equipment is incompatible
➜ If M is greater than or equal to 13 then your equipment is compatible

 ATTENTION: Measurements are taken with the equipment that will be worn when using the airbag product (jumper, additional protection, removable lining, etc…)
 ATTENTION: Measurements should be taken with the jacket stretched.

•  Motorcycle equipment (textiles or leather) is elastic and deforms (with use, the sun, your movements, etc.) allowing the airbag to find the space it needs to deploy at optimum pressure and absorb the energy of the impact.
• The In&motion airbag system can therefore be worn under any motorbike jacket as long as you follow the procedure above to make sure there’s enough room for the airbag to deploy.
