Best compromise between comfort and protection GregPaul’s first two paragraphs describe it well. Here is d3o’s description & spec’s, though I think the item pictured there must be the viper pro: http://www.d3o.com/wp-content/uploads/d3olab/D3O-Viper-Back-Protectors.pdf This has the d3o logo molded in, but not the Klim logo—Klim’s just marketing it. It’s flexible and conforms to your back. It even has a slight trough molded in for your spine. And the tapered edges are a nice touch. You’ll know it’s there when you put your jacket on, but it’s not distracting, and easy to forget about. As you can see from my photos, I trimmed it so as to not double up the padding under the jacket’s hump. It’s easy to shape with a razor blade, and to fold in half to mark/cut symmetrically. Also note I’m using it upside down, just because it fits into the jacket’s liner better. Of course trimming reduces the area protected, but for that area I think I have the most protection possible without diminishing the comfort or fit of my jacket. February 22, 2012
Excellent technology and a great price - but it's only CE Level 1 This is the d3O Viper Stealth model back protector, which is rated a CE level 1 back protector and so transmits no more than 18 kN (actually 12 kN per Satra testing) and is 11 mm thick. "CE level 1" is clearly engraved on the product. This is NOT the d3O Viper Pro model back protector, which is rated a CE level 2 back protector and transmits no more than 9 kN (actually 6 kN per Satra testing) and is 18 mm thick. i was looking for a temporary replacement for my "always" back protector for use during the hottest part of the summer. That protector has great specs (<3.38 kN), but is so dang big and so dang hot, I need help keeping my ATGATT committment. I would not recommend that anyone use a CE level 1 back protector, and certainly not recommend anyone rely on those thin comfort pads the garment manufacturers install as standard equipment. No one should be on a bike without a CE level 2 back protector. Despite my assessment of the adequacy of this particular model, I'm keeping this equipment and repurposing it. I've decided to keep the back protector and cut it into smaller pieces of armor. For example two chunks will make great hip pads - at 12 kN they might be the best hip protectors available. I've got additional ideas to reincarnate this pad. As best I can determine, the technology in this back pad keeps the promises made for it. It is very light, very comfortable, very protective and has a very appealing pricetag. August 13, 2011
Great replacement/upgrade armor First off, I do NOT own a Klim jacket or vest so I can't make any claim to its function in its intended use. I bought this d30 back pad to replace the skimpy foam pad in my FirstGear Rainier jacket (which I LOVE). The Rainier comes with d30 pads in the elbows and shoulders which pass the smack with a 2x4 test with flying colors, but the back pad is very thin (~3mm) piece of perforated foam. This assortment of pads is what gives the jacket its comfortable fit and trim appearance, but the back protection is in my opinion lacking compared to other jackets with CE armor. I searched for a d30 back pad to upgrade my Rainier and this Klim was the only one I could find. It is both thicker and wider than the part I am replacing and therefore did not fit in the armor pouch. So I had to sew a new pouch for the Klim part and chose to leave the original in-tact in case I wanted to refit the original. I have to say I am pleased with this pad, it is more conforming and does beef up the jacket weight a bit but definitely adds more protection that should have been there in the first place. It doesn't inhibit air flow through the armpit vents but does make my back a little hotter but not so bad as long as I am riding and not stuck in traffic (I've only used it in summer so far).

Works in the Traverse and AXO Enduro Jacket Bought the Klim D3O armor for my KLIM Traverse Jacket & Pants, it all fit great, with the exception of the elbow pads which I had to insert "backwards" way in order to get best coverage. I also purchased an additional back pad for my AXO Enduro Jacket, fit perfectly. June 20, 2011
love it Only wish I could get a D30 chest protector to go with it :) February 28, 2011
