Alpinestars Mens Non

Got this to update my Fieldsheer mesh jacket for my summer rides. It fits in the pouch as is. The cheap foam stock insert has bigger wings but this Back protector is almost the same shape. Happy to have this upgrade to my jacket.

Exactly as advertised, and fitted weill into alpinestars jacket. Arrived swiftly.

Fits like a glove and is easy to install in compatible Alpinestars jackets. Soft and agile, you barely notice it’s there. Very comfortable. I much prefer this to separate back protection for road riding.

I bought this to beef up the protection in a textile jacket that I ordered (Scorpion Eddy) as the installed padding just didnt seem like it was enough. It installed into the pocket in seconds, and I immediately felt much more confident in the safety of the jacket. The holes also allow for great airflow and doesnt feel constricting in any way.

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.

Der Rückenpprotektor passt perfekt in meinen Alpinestar Lederkombi, leichte montage. Er macht einen sehr guten eindruck und ist gut verarbeitet.

I bought this to insert into my Alpinestars Ageless Hoodie. I gave it mostly 5/5 stars, but 4/5 stars for comfort, as in my experience you can feel this a little more than the other models of Alpinestars back protector inserts. However, it is not bothersome, and it offers great protection. In installs in less than a minute. Size your back protector carefully - my Hoodie is a 2XL, and I bought the large model; if you wear anything less than a 2XL (XL or L), I would recommend going with the Medium, or perhaps even the Small if you wear a Medium or Small jacket / hoodie. All in all, though, this is a great product which I highly recommend!
