This chest protector is easy to fit, ergonomically constructed, unisex and actually consists of a duo: one to the left and one to the right of your central zipper. It is officially registered as 'Nucleon Flex Pro Ci', but if you remember 'very good chest protector', you'll go a long way.
Nucleon is Alpinestars own label when we talk about impact protection. To assess the impact of that (see what we did there) we need to look past the purely visual for a moment.
Impact protection of course has a clearly visible hatch: large vents that allow a lot of airflow, the color even ... it's all right, you see it and above all you feel it. These are lightweights that adapt. The advantage of own protection material is also that it fits in everything Alpinestars stands for, that's also a certainty. And at the same time that's also the disadvantage: it is designed for everything Alpinestars wears. For safety's sake we would keep the Nucleon-Alpinestars combination.
But, we were going to talk about the invisible hatch of this Nucleon Flex Pro chest protector: what happens on impact? Each Nucleon Flex Pro protector contains a packet of technology, R&D, know-how and experience. Specifically for the chest protectors, that means finding the balance between distributing an impact and absorbing it. Being big enough and doing your job well, that's essentially what it comes down to.
The combination of the polymers used, all high-performance materials, and of ergonomics (and therefore a good fit) makes Alpinestars speak of 'lightweight race and track protection'. And we must be honest: there is no reason to doubt this. On the contrary.
Alpinestars is not at his first test, the Nucleon Flex Pro technology has proven itself in demanding conditions more often and each new version or edition is a step further every time, being better, lighter.
