This Nucleon back protector thingy showed up looking all fancy but really it's just plastic and foam. It didn't paralyze me so I guess it works but mostly it just makes me look pro when I inevitably crash trying to impress my buds.

This back protector is awesome, I love how lightweight yet sturdy it is with the high tech flexible lattice shell, the foam padding absorbs shock great, it breathes well with the mesh to keep you cool, and has lots of adjustments for a perfect fit that stays put no matter what.

The Nucleon back protector has a ridiculous over-engineered design with space age materials and adjustability I'll never need, makes me laugh at how absurdly complex it is for a simple back protector.

I was happy with the Nucleon back protector which provided good flexibility and impact absorption thanks to the foam and shell design, though shipping was delayed the quality and comfort made it worthwhile and I'd recommend it to other riders looking for solid back protection.
