The RST Airbag Armour Shirt offers a CE Certification rating of C with CE Level 2 armour at the elbows and shoulders. It also offers an In&Motion CE back protector and is designed to be worn under RST's adventure X-Treme jacket. It is lightweight, breathable and moisture-wicking for maximum comfort. Despite the protective qualities, the silicone hem grip keeps it in place and is ultra-comfortable and lightweight. Please note this airbag system requires a subscription to In&Motion - with different variations available. For more information, visit: https://www.inemotion.com/myinemotion/en/moto-membership
