The Nucleon Flex Proi Full Back Protection Insert is an overpriced slab of concrete that pokes your back no matter how you move.
Myron –
The Nucleon Flex Proi back protector is pretty solid protection without feeling robotic, it fits nice, ventilates well, and is lightweight yet sturdy against hits so you don’t roast on long days shredding but still have protection when going hard.
Sidney –
The Nucleon Flex Proi back protector gets the job done with decent coverage and flexibility, though the style is a bit lacking compared to their previous model.
Louie –
The Nucleon Flex Proi back protector is lightweight and flexible while still providing good coverage and protection for trail riding.
Perry –
The Nucleon Flex Proi insert offers excellent protection and ventilation, I’m very satisfied after several weeks of use.

The Nucleon Flex Proi back protector is lightweight yet offers impressive flexibility and breathability, making it a great choice for motorcyclists seeking protection that moves with them.
Saul –
The Nucleon Flex Proi insert provides basic back protection as expected but with its ridiculous price tag and overhyped claims my hopes were unrealistic so I can’t recommend this overpriced letdown of a product.
