Alpinestars Nucleon KR-3 CE Level 2 Certified Back Protector - Lightweight Adjustable Motorcycle Armor for Racing & Street Riding Safety Gear

I needed extra spinal protection after two surgeries (unrelated to riding). I am 5’8” 165 pounds. I ordered a medium to wear under my Icon jacket. I removed the D3O back panel from the jacket to keep its fit, which worked well. The waist belt can be raised or lowered via Velcro bindings on the rear. I left mine in the factory position so it doesn’t interfere with the back brace I wear when riding. For my size and height the factory waist belt position was perfect in terms of positioning the side plates for rib protection.Overall this version is a bit pricey at $200 but considering the consequences of an impact without it, it’s a steal. I am always paranoid of getting rear ended by a texting teen at stoplights.If you can afford it, I recommend 100%. Hope this review was helpful. Stay safe out there!
