Value for money
Initially seemed like it was a good all round back protector at a good price. Having tested it on the track, I think I found it's only fault and broke 4 ribs in the process. The centre section of the protector protects the spine well but the edge of the protector is quite thick and is solid without the wavey absorption material. I just happened to land on this thick edge which had the "ouch" factor. Manufacturer should re-design the edge to be less thick or extend the absorption waves right to the edge.

Yup, the airholes are mostly closed off, otherwise excellent
As others have mentioned:

* The 3DO material is neat... firm but soft, moldable, and dentable with your thumb when push into it, but when you punch it, it feels like punching wood or drywall. Haven't crashed with it yet, so no feedback on that; sorry.

* The air holes that go through it aren't molded properly and most of them are blocked off... there are 59 holes total in five vertical columns. On mine, 19 of them were completely obscured, and 16 were more than halfway blocked off by excess material. I ended up trimmed all of the holes to make them near-perfect... took about half an hour using the wife's manicure scissors. Could take less time, but I'm kinda OCD and wanted to make the openings as clean and round as possible. Not a big deal to have to spend the time and effort to do this, but still annoying that the product isn't manufactured properly at the factory.

* The Klim 3DO back protector is 18mm thick as advertised. I think this is about the perfect thickness for decent protection without it being bulky and significantly changing the fitment of your suit. I couldn't really feel it in place immediately after zipping into my suit, in terms of it being there, the weight of it, etc; it quickly molds to your body with heat even better. Speaking of heat: yes, I could feel that my back was hotter with it in place than wearing the leather track suit before... see above about cleaning up all the ventilation holes.

* I was happy that this back protector fit the mesh pocket in my super old-school (probably 15+ years old) Euro 52/US 42 Fieldsheer suit without any trimming. MEASURED DIMENSIONS: 17 3/8" top to bottom, 10 5/8" at widest part (across the "wings"), 7" to 7 1/4" across the top section (which is 3" tall from the top to where it goes wide for the "wings"), 6 5/8" across the bottom section (which is 5 1/2" tall from under the "wings" to the bottom). Trimming it would be super easy with any sharp pair of scissors though.

* The Klim 3DO Viper back protector weighs 1 lb, 1 oz (482 grams).

Tested it first ride
While it is by no means a full race quality piece, it does offer a significant improvement over the cheap foam inserts found in many jackets. Compared with my stock Alpinestars protector, it added a bit of weight and thickness to my jacket, but overall comfort was not really affected due to the flexibility of the D3O material. I have not ridden with it long enough to get a good sense of airflow.

That said, I had the unfortunate pleasure of testing this protector the first ride after I installed it. A little over a week ago I was hit from the rear by a sliding bike. The end result was me ending up on the ground on my side, then flat on my back. While I do have sore back, I fully feel that the protector helped keep the injury to a minimum. So once again, it is not a hard race level protector, but it is a very good compromise for something you can comfortably use everyday instead of leaving it at home.

Crash tested
I've had D3O padding in my street jacket for about a year now and always loved the fit and flexibility. A few months ago, I decided to upgrade my track suit's armor to full D3O padding. Last month I crashed fairly hard at the track, missing a corner at about 50-60mph and losing traction in the grass infield. I slammed down hard on my R shoulder, my R leg slid under the bike for a while, and I spent a fair amount of time tumbling. My only major injury was a ligament strain in the R shoulder that I'm fairly sure could have been worse. I can't say for certain that the D3O worked any better or worse than other padding would have, but I walked away. I'll keep on using it for as long as it's available.

Best CE level 2 back protector for summer
Klim weighs 1lb/2oz (509g) (exact dimensions at d3o site)
Sas-Tec weighs 12oz (342g)
Can of coke weighs 13oz (368g) (NOT level 2 protection...)

The Klim has a clever channel design that actually works. The 1cm deep channels are against your back, and the holes let the hot out (I don't think there is a level 2 back protector that could have a 5/5 rating and still work, so 4 is top until NASA comes up with some miracle space thing). It works better than anything I've tried (level 2). It is heavier, but visco-elastic and conforms with body heat so you will hardly notice it. It is thinner than the Sas-Tec. I have both and either one gives me confidence it would help in a meaningful way during a getoff. However, the channels system on this one is very clever. I had to clear out the vent holes with a dremel as some of them weren't punched all the way through. Big whoop. It is extremely flexible (see pics) and you can trim it to fit if it's too big. This is the 18mm thick Viper, not the 11mm one. I have a leather jacket (1.3-1.5mm) outfitted with all Klim, and it feels like an extra sturdy jacket, not a suit of armor. The Klim just warms up and disappears.

Comfortable fit, reassuring protection
This back protector fit well into my Joe Rocket leather jacket, after stitching up the bottom of the pocket to keep it high enough. Protected me well in a crash with a city bus last week!

Good upgrade
Upgraded the stock CE level I back protector in my Icon Hypersport prime jacket. Heavier and thicker, makes me feel way much protected than the original. Have ridden with it several times now in Florida, and it doesn't seem to limit airflow anymore than the original. That said, prepare to punch or cutout the holes yourself in any of these D3O back protectors because at least half are plugged. Slightly wider and taller than level I protector but still fits the pocket.

Great product and very affordable.
It's rare you get CE 2 level protection for under 40 bucks! Ive bought this back protector twice now to cut down to fit in my jackets, and its easy to cut down as long as you have nice strong scissors. And did I say CE level 2 for under $40?

Great product, but one size
Light, thin, flexible and not a heat sink.
While it lacks rigidity, it seems to be fairly protective (have yet to test this thankfully).
The only issue, to no fault of it's own, is that it's one size fits some. I usually wear an Alpinestar Verona jacket (not the "air" version) and the pocket is way bigger than this protector. Due to the space, the Klim sits low in the coat and flops some left to right.
If your sure this product fits your jacket well, it's great.
