Alpinestars Mens Non

Have an older Alpinestars leather jacket the recently went through a very thorough restoration. I used this to replace the older foam back protector in the jacket. Breathes much better and is much more comfortable!

Lightweight comfortable, a solid back protector. Nothing bad, nothing mind blowing.

As described

Top protection qui couvre tout le dos. Prend bien la forme du dos et est parfaitement adapté aux vestes prévues.

Ottimo prodotto di qualità arrivato in 3 giorni

Fast delivery, very happy.

Excellent delivery and product as described

Perfekt im Sommer, da endlich die Luft am Rücken zirkulieren kann. Die anderen Protektoren haben zu wenig Belüftungslövhet und man ist danach komplett verschwitzt.

Ligera, no molesta y no da calor

I guess its difficult to be sure just how good this product is until Ive taken a slide down the road on my back (!) but, hoping that never happens, I can say the Nucleon KR-2i seems to be well made and durable whilst still relatively comfortable to wear. I bought the KR-2i to replace the padded foam that comes supplied with the Alpinestars Jaws leather jacket, and it does the job well, fitting snugly into the back of the jacket and sitting comfortably against my back when riding. Its an obvious step-up in shape, looks and feel compared to the piece of floppy foam, and as its CE-Level 2 certified it should be far more protective (for info the similar Alpinestars KR-1i is also CE-2 rated but is a little thicker, a little stronger but more rigid). The KR-2i is noticeably thicker than the foam it replaces (about 3 times thicker) so you do feel the difference when its in the jacket (no more pies for me!), but its malleable and bends to fit the contours of the back so its surprisingly comfy. Its comfortable enough to wear with the jacket on when walking about for the day too. Other noticeable positives are it breathes well and allows air to flow nicely within the jacket, and it comes in a sealed branded packaging with a silica gel bag and instruction book. It feels and looks like a premium product. Im pleased to have upgraded to a potentially back saving quality protector compared to the freebie piece of foam that wouldnt be much good much if the worst were to happen, and I feel more confident with the KR-2i in place when I ride. Definitely recommended.
