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).

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.

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!

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.

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.

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.

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.

Richard L on Aug 29, 2016
The back protector that came in my Klim Latitude jacket is very thick, very stiff and very hot. I wanted a CE protector that was lighter, more flexible and cooler. This one is certainly lighter, more flexible and more comfortable. I won't know about being cooler until I ride on a hot day, but it's a major upgrade regardless.
Matt L on Aug 27, 2016
I chose this because I love the comfort of the D30 armor. I changed out the lightweight back protector that came with my Scorpion jacket. I am now safer and more comfortable! I highly recommend this product.

Received my two Klim inserts today and they fit perfectly into my First Gear jackets. Question......which side goes against your back? The ribbed side or the flat side? This may sound like a dumb question, but I just want to make sure I am inserting it correctly!
These inserts are so comfortable and I am glad I got them to replace the foam inserts.
Shawn K on Sep 29, 2013
BEST ANSWER: The air wave is for ventilation so with the waves against your back allows air flow. I had the same debate of when I received mine. its very comfortable. enjoy and I wish you never need it.
Hey there,
How does this compare to the Forcefield armor in protection and flexibility?
Thanks
Kyle W on Aug 14, 2013
BEST ANSWER: The Klim Viper T5 is the same CE 2 rating as the Forcefield, but it offers more flexibility, similar weight and is less expensive. I find it to be an overall better value and have one in my jacket.
Can this be cut to fit any size/brand back pocket? Firstgear jackets have small protectors.
A shopper on Mar 29, 2012
BEST ANSWER: Yes, the Viper T5 D30 Back Protector can be trimmed to fit. You may also be interested in the SAS-TEC back protector as well; it is reportedly easier to trim.

Please note that trimming either of these to fit will void any manufacturers warranties.
Hi,
is this the viper stealth: 11mm or the viper pro 18mm ?
A shopper on Sep 1, 2011
BEST ANSWER: It is the Viper Pro, size (L)arge. 274mm wide, 444mm tall, and 18mm thick. Full specs at http://www.d3o.com/wp-content/uploads/d3olab/Viper-Pro-L.pdf
What are the Dimensions on This Item ? I Ask because I know that D30 is some pretty high tech armor and am wondering if I can fit this in the pocket on my current riding jacket which is not made by Klim. This looks like it could be a VERY nice and reasonably priced upgrade to a number of jackets that come with lower level PE padding
A shopper on Aug 27, 2011
BEST ANSWER: I will have to measure when I get home, but it is easily cut to fit any pocket. Due to it's use of non-newtonian foam/fluid, cutting it will not lessen it's protection, although larger is always more protective.
Has anyone tried this in an Icon Overlord Prime leather jacket? Would it fit without having to trim it?
Frank C on Oct 14, 2013
BEST ANSWER: Yes it will fit. I've tried it in an icon overlord hero prime 2xl, overlord type 1 jacket XL and a dainese super speed jacket 58. No trimming is required. It's also a very comfortable choice.
Revitt Sand Pro 1 jacket, is the armor smaller or just right (height and width) for the jacket's back protector slot. From what I understand I can trim the armor to fit without compromising it's structural integrity, is that also correct?
A shopper on Mar 19, 2015
BEST ANSWER: It's just a little too long for my tourmaster, and I needed to trim it. I't is fairly large. Iv'e already crashed landing on my back hard, and on a rock. Bruised the ribs, and displaced a rib where I landed on the rock. I can't imagine what it would have been without armor. My Forcefield armor on the hips, coccyx, and thighs had no pain; it's thicker armor, and I felt nothing in those areas. Hard to tell if I would have had the Forcefield back armor would have been more cushion on the back? I know for sure without this high rated armor, I believe there would have been more damage. And, yes you can trim the armor to fit.
I have a Dainese Frazier size 54 and was wondering would this fit without trimming?
Edward C on Sep 19, 2014
BEST ANSWER: I purchased the Viper and easily trimmed it to fit my First Gear jacket. You can use normal wood working tools if you first put it in the refrigerator or better yet the freezer. Sorry no experience with Dainese.
Will this back protector work with the Firstgear Mesh Tex Jacket?
A shopper on Sep 30, 2013
BEST ANSWER: I just received a medium tall Firstgear Mesh Tex and the Klim back pad, a D30 Viper Pro size large, is smaller than the pack pad pocket. I think an extra large D30 Viper Pro would fill out the pad pocket completely and I will be ordering one. You need to measure your back pad pocket. I also got a medium tall Firstgear Adventure Mesh and the back pad pocket is smaller so the large D30 Viper Pro fits perfectly.
Does the wave pattern go against your back for airflow, or away from your back to allow better flexibility?
A shopper on May 7, 2013
BEST ANSWER: The wave patterns lies against your back to provide more airflow. That said, this insert is still one of our more flexible back inserts all around.
