Dainese D-Air Long Sleeve Smart JacketDainese developed what can be considered the life jacket of motorcycling - now with long sleeves and pockets. It's safety equipment that you hope never to use, but you should never ride without. The Dainese Smart Jacket brings Dainese's MotoGP experience to a standalone airbag vest that you can wear in a variety of situations. D-air airbag technology distilled down into a vest (sleeveless jacket) that can be folded and easily stored in a bag, top box or backpack. Wear the Smart Jacket over or under any jacket or outfit. Its sensors and activation does not rely on a specific shell to house the technology so you can wear the device with your leather street jacket or your birthday suit (not recommended). A complex algorithm recognizes when you're in danger so it can inflate the airbag post haste to protect your back, chest and vital parts; no tether to your motorcycle required.Put on the Smart Jacket, secure its fasteners and you will be protected for 26 hours on a fully charged battery. The Dainese Smart Jacket uses seven sensors to analyze data at 1,000 times per second so the vest will be ready to deploy at a moment's notice. MotoGP airbag protection can now protect the common rider outside of the professional paddock.Note: Customers recommend ordering one size larger than your typical jacket size.Features: D-Air, MotoGP airbag technology Ventilated and breathable Sensor waterproofness 2 outer pockets Waist adjustable system CE level 2 armor at shoulders and elbows Seven on-board sensors Data is monitored 1,000 times per second Algorithm detectslow-sides, high-sides and object/vehicle and rear-end collisions Collisions are detectedeven when stopped, e.g. rear-end collision at a stop light 26hr battery life No hard-shell parts - airbag provides protection only when needed Chest protection meets or exceeds CE Level 2 for airbags, transmitted force is <2.5kNStandard armor CE level 2 transmits<9kN so the airbag disperses over 3x more energy than its rigid counterpart Back protection meets or exceeds CE Level 1 for airbags, transmitted force is <4.5kNStandard armor CE level 1 transmits<18kN so the airbag disperses over 4x more energy than its rigid counterpart
