Alpinestars Mens Non

Worth replacing the thin useless piece of foam.

alpinestars is always perfect

This is a nice piece that fits right into my Alpinestars jacket. The jacket unfortunately did not come with a back protector but I sure was glad to find this one. When I opened up it was very flexible, which is good because you want that to conform to you back to take the shape when youre riding. I put it in my jacket and it fit perfectly. I really liked how its light weight and flexible with CE protection.

Fit my X-Large Alpinestars T-GP Plus R v2 Air just fine.

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.

Producto genial, se adapta a la postura y da una sensación de seguridad

Excellent product!

Adds the protection I was looking for! My jacket is a mens 2xl and this fits great.

Perfetto per la giacca Caliber Alpinestar.
