Lightweight, super comfortable, ultimate air flow, quality materials, excellent design.

I was going to buy the Forcefield Pro Lite K but, I'm glad I waited for this to arrive.

Fits great in my Avro D1, Perforated Race D1 & Super Speed textile jackets.

Placed this in my Dainese Jacket and it fits perfectly. Flows air well and can tell that if I needed it, the protection would be there. But damn if this thing is just ungodly uncomfortable. Seriously, there is no flex to it. Its like riding with a piece of plywood as your back protector. I know the waffle shapes are there to flow air well but I have noticed that my leather is starting to show these shapes. Was worried it was going to ruin my jacket so I placed a thin piece of cardboard between it and the leather. If I had to do it again I would have purchased a different one, mainly the AS.

It's very flexible, you'll hardly notice it.

Far more air flow than solid design spine protectors - even those with much less protection.

I'm 6' 2" with a normal to relatively short torso, and the G2 leaves a couple thoracic and lumbar vertebrae unprotected. Wish they would offer 3 sizes??

Dainese needs to release a 3 size system for back protector inserts. G1 and G2 just doesn't cut it when you are "in between" sizing. The cut off to move up to a G2 is size EU50 typically. If you are a guy in the 46-48 range, this is challenging, as you will likely find the G1 far to small. On the pro armor, feels slightly smaller still compared to the Manis.

Size Medium ( read as G1, G2, G3 Dainese!) would be perfect for riders in this size range.

I fortunately find that my G1 Pro Armor fits particularly well in my EU48 Super Speed jacket. I've since purchased an Alpinestars Nucleon insert in size Medium and they fit perfect in my Dainese textile jackets. The A* Nucleon was $30 cheaper as well!

I bought this back protector (G2) for my Dainese Razon jacket. I also have the Manis D1 and Alpinestars Nucleon KR-2i.

While it is more comfortable than the Manis, it doesn't quite match up to the flexibility of Nucleon, with the large Nucleon being the same dimensions as the Pro Armor G2. It's just too stiff to be comfortable, and I'm always reminded that it's there.

Love this back protector! A lot more flexible, better air flow, and fits the jackets (Women's Racing D1, Hydra Flux D-Dry, and Air Crono) better than the Wave ever did. Definitely happy with this purchase.

Bought for my Dainese jackets and primarily for my Dainese Air Frame D1 Mesh jacket - air flow is best in class, it is comfortable (pliable) and rated for CE2 protection... outstanding. Even fits in my AlpineStars jacket too. Only knock is the typical premium price for the brand but that's part of the package with anything Dainese.

Bought the pro armor back protector along with the fighter jacket. I'm 6'1 and wear a size 56 jacket and the g2 fits snugly into the smaller back pocket of the jacket, sitting between the lower part of my shoulder blades and upper lumbar.Best things is that it flows air like it aint there. I trust Dainese that they did their homework and it will do it's job when/if shtf.
My only gripe with this model is that it's quite stiff and sticks out when riding full tuck. This ultimately stretches out the leather in the back and might leave unsightly hexagonal marks.
I currently switch between an r1150r, f800gs and an 821 monster so this isn't that big of a deal for me. However, sport bike brethren beware!

I haven't crash tested this yet, thankfully, but if Dainese put it out, I'm sure it holds up fine. Honestly, I'm writing this review in hopes that Dainese reads it because the quality control dept. isn't too picky... at all. I'd hate to see what a no-go product would look like.

Bang for buck: I think it's pretty steep to charge this much for a plastic-injected piece of rubber (not sure what kind, specifically), but as a mold-maker, I know what it costs and how many of these they can crank out in an hour (let alone a day/week/etc.) However, throwing a demon logo on anything is going to bump the price.

Protection/Durability: As I said, luckily, I haven't crash tested this. I just have to go off the fact that it's Dainese and it's going to do what it needs to when the time comes.

Features: Kind of hard to rate on something like a back protector but I'll use this section to note that there is a ton of flash on this thing. QC over there is lacking in a big way. Looking at it now, I don't see a single web or edge that doesn't have flash (small amount of excess plastic/rubber from molding process). For $90 and a Dainese logo, when I got it I mumbled "Really?" when looking it over. This has no effect on function but c'mon, guys, have some pride in your work/product. Even if it's something that doesn't show when riding.

Comfort: Feels nice. It's easy to forget it's there and after a day or so, you forget it's there completely.

Style: ?

Airflow: Wearing this in the back of my Racing D1 feels fine. It never seems to make my back sweat, even in hotter weather.

I really like this new back protector. It fits perfectly in my Dainese fighter jacket. It is quite flexible but I was expecting to be even more from the revzilla video review. Still it is better then the pro-lite back protector, slimmer and more flexible.
