Rukka D3O Air Knee and Shin Protector

Rukka D30 Air Knee Armour

D30 Air is a patented protective material that combines enhanced chemistry with product engineering to produce high performance shock absorption and impact protection solutions. A brand new D30 Air material has been developed especially for the Rukka protectors. This new material has some unique characteristics that provide enhanced versatile and flexible protection. The material contains intelligent molecules that flow freely when moving, but on shock lock together to absorb impact energy, instantly returning to their flexible state. D30 Air does not go hard when hit, the molecules lock together to absorb and spread the force, significantly reducing the effect of impact. D30 Air disperses the force of impact, drastically reducing transmitted force and minimising the risk of injury. The protective qualities are retained after repetitive impact.


  • High performance shock absorption.
  • Trusted protection.
  • Maximum flexibility.
  • Extremely comfortable.
  • Tested according to CE Standards.
  • Conforms to CE1621-1

D30 Air Rukka Knee/Shin Armour
Used the D3O to replace bulky Alpinestars knee armour. Much better fit and feel hope I don't have to try how good they work.

Amazing quality and safety
I came off the bike and did hit my knee at edge of a pavement at quite some speed. Without the armour I wouldn't have a knee but actually I didn't even have a bruise. Highly recommended by me.
