You can find the Nucleon KR-2 under the category 'back protectors', but actually we should come up with a new term in this particular case. The Nucleon KR-2 is an all-round top protection and at the same time a lightweight that boasts a level 2 CE certification (EN 1621-2:2014). A lot in one protector, in other words.
With a removable shoulder strap and a wide, ventilated, adjustable kidney belt, it looks like you're getting ready for battle when you put on the Nucleon KR-2. Yet at no point does the whole thing bother you. The lightweight, elastic memory foam with integrated hard protector on the spine provides optimal protection. Kidneys, ribs and shoulder blades benefit from this, while the whole unit continues to breathe and is even equipped with an air-cooling system.
From an up-to-date, contemporary armor, you can also expect that it doesn't feel like you've just put a shield in your jacket. The Nucleon KR-2 follows the profile of your back and is designed to adapt to your specific anatomy.
This makes it the perfect piece of protection for long days in the saddle.
The whole thing weighs - depending on the exact size - about 700 grams. The size varies per size, but both length and width are a bit wider than what you can expect from most other back protectors.
