Great Product! For the price you can't beat it. Finally replaced the back armor in my Firstgear Kenya jacket. Fit perfect, barely noticeable and light years beyond the original. I replaced the back armor in my Revit Air jacket with the recommended See soft armor. Yuck! Might as well have a piece of plywood in there. Replacing that now with D3o armor. Love it! It does have ventilation and flexes with my body. You will feel it if you stretch against it, otherwise you won't notice it. Best money you'll spend. 2004 BMW K1200rs 1992 BMW K75s July 15, 2014
its great light, cheap and works great. it is build in an itelligent polimer. July 13, 2014
Great product! The material in this back protector is so interesting- moldable to your back when warm, allows air flow, but super protective. A sales rep showed me how it absorbs impact by hitting it with a metal object. I was sold. I use it in my Dainese Laguna jacket and love everything about it. Highly recommended! June 30, 2014
Looks and Feels Good Good fit and decent weight. Only issue is what other have said about having to open the vent holes manually as most are closed. Easy to do with a sharp knife. June 24, 2014
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. June 24, 2014
CE level two protection, very affordable I haven't had the opportunity to test it out yet (knock on wood), but it is a CE level 2 protector, and you can't beat the price. June 17, 2014
bought it as replacement for better protection Hopefully, I will never have to state in a review whether it worked or not. Peace of mind is worth whatever additional cost, in my book. After several calls made to RevZIlla inquiring on replacement pads for my Cortech GX Sport Air 3.0, I risked it & purchased it. I can say that NO customization of original pad pocket had to be made. It fits perfectly & covers the spine, it may be better just an inch or two higher, but...Ill keep it where its at. Hope this helps someone. Shiny side up, rubber side down! Better safe than sorry!

Excellent and comfortable! I originally purchased the SASTEC level 2 back protector but during the summer, even with my breezy textile jacket, the SASTEC was like a windproof shield on my back. Finally switched to this D3O viper and happy to report it is extremely flexible and lets air flows well. It also is very solid when you punch it. June 14, 2014

RevZilla Store asked: Why did you choose this?
Robert T: level 2 protection - best protection you can buy - worth twice the price if you go down! Jul 16, 2014
Alfred C: As I get older, gear that will help me keep more of my skin in an unplanned get-off becomes a bigger priority. Protecting the back means getting to walk away rather than being rolled away. Also, the improved impact resistance is simply a huge deal. Blunt force trauma kills more motorcyclists than anything, and hitting a tree while "t-shirting it" is guaranteed to leave behind some of your skin, which can't be grafted back on as easily as leaving your skin intact with better, safer riding gear. Jul 15, 2014

Urooj A: Best back protector for the Price. Best back protector to where I trust my life in it. Just happened to be a great price. I added this into my Dainese Shotgun Jacket. It's as if they were made to go together. Research Klim, this material will protect your back. Even when it's not, It's not bugging you, bulky, or uncomfortable. I'm very happy with this purchase. Great recommendation by the Team at Revzilla. Thank you! Aug 30, 2013
Hao D: Didn't want to wear my race back protector on the street. These were a great choice without sacrificing airflow or protection. Aug 28, 2013
Gaurav K: Was looking to upgrade my back protection in my alpinestars jacket and D3O is one of the best options. CE2 certified, comfortable to wear and less rigid than my previous back protector despite offering a higher level of protection. Great buy. Been using it for 4 months now and think this is money well spent. Aug 21, 2013
GREG B: I put this in a cheap Bilt Jacket to upgrade the armor and replace the crappy foam back pad. It fit great and feels good in the jacket. Would recommend this to anyone looking for back protection Aug 19, 2013

Edward W: 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. Aug 15, 2013
Reply to Edward Good answer? Yes (2) No (0)
DAVID E: I do not have any experience with the Forcefield armour. I am however very satisfied with the T5 Back Protector. I bought it to replace the thin foam pad which came with my First Gear Jacket. If you have seen the OEM pads these jackets come with I need say no more. The T5 is a PROTECTOR not a thin pad. It is a little heavier, not as flexible as the OEM, but it breaths well and I have not had any issues with it at all. I truly do feel better about my safety in a get off with the T5...I made a good choice. I have no reservations recommending this piece of equipment to anyone looking to upgrade to more substantial protection. Aug 17, 2013

Randy H: Very flexible and heavy.

The ribs kind of make it softer, as it is pretty spongy in a hi-tech way.

I ended up putting the amour that came with my Klim Latitude Jacket back in because the D30 was so heavy. I hear the D30 that comes with the Latitudes now is thinner, therefore less weight.

But it would be the best amour if a person hit the ground.

RevZilla: 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.

TwoWheelTom: If you were to use a SHARP utility knife and lay your pattern out on top of the pad, it could be cut to fit. I would first trace your pattern on the back side, as it's smooth and a better writing surface, and then cut accordingly. Jul 12, 2012

Shawn K asked: 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.

Frank83: Very flexible when it needs to be. It firms up instantly upon impact. It kinda feels like a thick slice of well done steak. It is a little stiffer when it gets down below 35 degrees F and gets softer as it gets warmer. Jan 24, 2013
Reply to Frank83 Good answer? Yes (0) No (0)
Peterpq3: I think it would fit fine. It is extremely flexible and has an almost "not there" feel to it. If it is too big, you can trim it, but it fits into my jackets fine. Apr 3, 2013

Answer this · Send to friends Good question? Yes (0) No (0)
Donald R.: No.
But it can easily be trimmed, and I trimmed mine to be larger than the OEM "pad" in my transition 2, which is a plus. I used kitchen shears, but heavy duty scissors should do the trick. It's not particularly pretty, but nobody's going to see it anyway.

A shopper asked: 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.

sxt173: 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. Apr 17, 2012

Chris L: It will fit any of the built-in spine protector pockets. Unless the jacket is very fitted it may move around. I'd recommend fitting it first and adding a couple stitches through the liner to keep it in place. Very light and CE-Level 2. Apr 24, 2014

Alainna W asked: While I understand that trimming the protector voids the warranty, does trimming it affect the protection? Is it still CE2 armor if it is modified? Apr 10, 2014
Answer this · Send to friends Good question? Yes (0) No (1)
Michael Z: I don't have extensive knowledge about what the CE levels measure, but my understanding is it just measures how much impact will be reduced from impact. If you base it off of that understanding than trimming wont affect the CE2 level, but only the area of coverage. So as long as you're not cutting it in half and just trimming the outside to make it fit in the jacket you'll be good to go. Ps: this back protector is awesome :) Apr 15, 2014

Bruce P: All of the above answers are well thought out about this product and this is the only back protector I prefer. With all that has been said.... yes, trim carefully for your fit. After all, I would much rather have a trimmed back protector inside my jacket than NO Back Protector at all! May 2, 2014
Reply to Bruce Good answer? Yes (1) No (0)
John H: I think Michael is technically correct. However, the idea of all armor is to spread the energy from an impact across a wider area. The more you cut, the less area there is to absorb the energy. I'd cut very carefully and cut the absolute minimum in order to get it to fit. Apr 22, 2014
Reply to John Good answer? Yes (1) No (0)
Chris L: Having owned most of the spine protectors on the market I would say this is already the smallest option (other than those unprotective-junk HD foam options). Don't know why you'd need to trim it. Apr 24, 2014
