After inflated, don't forget to change the cartridge!
The air bag refill developed by In&Motion is the first equipped with 4 independent gas cartridges. Each inflates a specific part of the airbag. The inflation time is thus the fastest on the market. The shape of the cartridge, flat and curved, allows a comfort and discretion hitherto unequaled.
I think it is difficult to do better.
