AlpinestarsNucleon KR-3 Men's Off-Road Motorcycle Back Protector - Black/Red/X-Large

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!

The feel is good and fits really good as if it molds to your backOnly bad part is that it's a little bulky with a tight 1 piece suit on, it pushes the hump out it bit on your back so it feels like the back of my helmet hits the suit hump

Product arrived fast and fits great. The ergonomics inside this product are amazing. It preformed just as expected by molding to your body as the gel foam warms up to your body heat. The kidney protectors are very comfortable in up right and even on an aggressive position to the point you don't even notice there are there. The elastic waist band wraps around you firm and it moves well with your body. Note to people that want to wear this under your leather jacket. It is not bulky as a lot of people described on videos and I wear my Dianese leather track jacket fit to my body. Overall excellent product in my opinion.

Bought this to solely to wear under my A* track suit and ended up removing my insert for my street Dainese jacket and now I use this all the time. Size chart was spot on and this thing disappears on me once it’s on. I don’t even think about it.

Great spine protector. I use on the track under leathers, and under my airbag jacket on the street. So comfy, you forget it’s there, except, the extra spine support keeps your back from getting near as tired in ling touring days across the desert. A no brainer. What are u waiting for?

Excelente calidad y producto, vale la pena invertir.

hard to fit with suit.

Speedy delivery & accurate sizing. Thanks!

Me agradó mucho la comodidad y protección así como la calidad de esta espaldera Alpinstar Nucleon KR-3.Sin embargo me gustaría completar con la pechera KRC para tener una protección completa.

Le Velcro ne tient malheureusement plus après juste une saison d'utilisation (non intense).. Je suis obligé de le replacer presque à chaque fois que descends de la moto.Autrement j'en suis très satisfait, si il n'y avait pas eu l'histoire du Velcro qui se défait tout seul, j'aurai mis 5 étoiles.Je recommande malgré tout

Ideal para carretera, consigue que tu posición sobre la moto sea mucho mas ergonómica y relajada gracias a sus sujeciones lateralesBuena calidad y muy cómoda, propia de la marca

Great Great product very happy with it

Il paraschiena Alpinestars Nucleon KR-3 è il più bello e particolare da vedere. la trama 3D della parte centrale attira l'attenzione per com'è concepita e realizzata. la costruzione e i materiali sono al top. sono alto 190cm e la xl mi va benissimo. è molto comoda quasi non si sente però aiuta una corretta postura in moto. i paracostole sono ottimi. lo spessore non intralcia minimamente la vestizione. è traforato e molto traspirante. per riporlo non si può chiudere a "libro" ma è abbastanza flessibile da entrare nel bauletto e da farci stare anche il casco e altre cose. è il top come estetica, protezione e comodità. non potete sbagliare. sono molto soddisfatto del prodotto grazie!!!!!!!!!
