> 3 dayI got this to replace the foam pad in my Alpinestars T-GP Plus R Air motorcycle jacket, and as expected, it dropped right into the jackets back protector pocket. This circulates air as effectively as my jacket itself, so unless I walk around with my jacket on, or get stuck standing at a stoplight for a long period of time, I dont even notice this back protector is there. Its a dense rubber, so it may not be top of the line for safety gear in this regard, I think its a great compromise if you want a cool (temperature) setup that affords some more back protection. Im very happy with this, and although Ive thankfully not had to test this protectors capabilities in a crash, I feel better knowing I have it should I go down while riding.

> 3 dayI’ve bought an textile Alpinestars jacket which happens is without a back protection and bought this . So it fitted perfectly and also the jacket is summer/spring , so basically I was using just the outer side of it with the protector and it was really light, but very efficient. Thank God I haven’t felt to see how good is it , but as a long term rider I know which stuff are good . Highly recommended

> 3 dayAwesome quality as always, yes these are expensive for what they are but you get what you pay for. I ordered two sizes one for me and my wife, when it comes to her protection I always get the best, this doesn’t disappoint fits great in both of our jackets.

> 3 dayIl prodotto è molto ben fatto e conforme alla descrizione, purtroppo ho dovuto fare il reso in quanto ho sbagliato il modello, questo non è compatibile con il mio giubbotto, peccato perché molto leggero e flessibile, molto comodo.

Greater than one weekI 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.

> 3 dayGot 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.
