The Zip'In 2 allows for greater mobility because of it's fitted design. Additionally, it fits excellently into the jacket, has a greater volume of protection in the chest area and a lower cartridge weight. Thanks to the central zip, the airbag can be worn alone or as an invisible lining under compatible Zip'In Clothing to avoid damaging the airbag in case of a fall. *Please note, that it is crucial to never wear the Zip'In 2 with non-approved clothing - This may impair the airbag inflation and may not protect you properly.* The airbag lining offers a large protection volume and is equipped with a mechanical system that is ready-to-go and easy to reuse. With its ultra-fast inflation (100 ms), the Zip'In 2 ensures optimal protection of these vital areas: cervical, back, pelvis, sacrum and thorax before impact. It comes ready-to-use with: • 1 gas (CO2) cartridge • 1 lanyard • 1 saddle strap • 1 Allen key • 1 user guide
