We offer this piece in Level 1 ("Stealth") and Level 2 ("Pro") variants—one is about shy of 1/2" thick, the other is a full 1" thick. Aside from the Level/thickness differences, these have the same profile. See below of full specs. 

For most applications we prefer the Level 1 -- which is way better than Level Zero; and not as cumbersome as Level 2. But we'll never argue against more armor. It really comes down to what is comfortable, and what you'll wear every day.

This Viper Pro back protector is an industry standard, and comes stock in our own armored waxed cotton Robinson Jacket, and our Leather V7 Jacket. It also comes stock in every Aether and just about every KLIM jacket we stock.

Features:

  • D3O patented technology
  • CE Certified to exceed the performance requirements of EN1621-2:2014, Level 1 or 2, respectively.
  • Airwave Technology for improved airflow
  • Flexible ergonomic design for comfort and protection
  • Thickness: 11mm for Level 1; 18mm for Level 2
  • Available in five different sizes, determined by torso length (cm)

About The Brand

D3O is a leader in performance motorcycle armor. Its telltale orange material is instantly recognizable as a trusted name in safety. The secret is a non-Neutonian material that stiffens upon impact, but still remains comfortably pliable. The UK based company makes a wide range of armor options that are stocked in some of our best products—including our own house-brand jackets.
