Klim D3O Viper T5 Pro Back Protector 4.7 5 120 120
Much better than the protection that came with my jacket Although you definitely know that it is there, this light weight armor really had little impact on how my (Triumph) jacket felt when wearing it. The foam folded easily to fit the pocket in the jacket and covered the entire back area perfectly. I'm not sure how it does it but this material really does go from soft foam to hard armor when it hits something (tried punching it before installing). Makes me feel much more protected at a relatively very low cost. April 14, 2014
Great addition to a jacket I have a couple alpinestars jackets that I took the back foam out of because I didn't think that it offered much protection. I bought a knox protector for the track but was missing one for the day to day. I had seen this 3D0 stuff before and figured I would give it a shot. If you are looking at this, you are probably in need of a back protector. I would recommend buying it. Inexpensive and fits well. April 7, 2014
Never leave home without it! Chose this back protector after reading all the reviews on all the available brands and then finally talking with an adviser at RevZ (thanks!). Can't compare to any other brands by first hand experience. It fits into my Triumph McQueen (medium) without any cutting. Adds weight, bulk, heat (of course) to jacket. Unfortunately, that's the side effect of having something that will protect your spine. It does bend and contour to your body fairly well. Get it or get one of the others. If you're reading this you're obviously among those of us smart enough to know it's money well spent. April 7, 2014
Great product Great protection went down on a low side slide and rolled a bit and the armor did its job glad I wasnt wearing a foam pad . Good for summer heat too April 7, 2014
Great product, haven't had to test it for real This in theory is a really great product. It is genuine D30, which means that in normal temperatures, it is flexible like rubber, but hardens to solid when under impact pressure. Only issue here is that if you are a cold weather rider, this isn't going to work for you. Under cold temperature, the D30 becomes hard as regular armor, which defeats the purpose of the flexible armor. In normal temps above 40 degrees F, you'll be fine. The sort of wavy pattern makes it so it will flex really well vertically, but not so much side to side. It's in general very comfortable, and MUCH lighter than normal level 2 rated CE armor. I honestly can't attest to how well it holds up in an actual crash, but from what I've heard through the grape vine, it provides a lot of safety, but doesn't really take the shock away as well as traditional hard armor. If you're worried about fit, it's really easy to use some tough scissors to cut through the D30 to size it to the pocket you need it to fit in. I would absolutely recommend this for someone who is looking for better protection than normal tempur foam, but isn't looking for the best of the best when it comes to shock absorption, and isn't riding in near freezing to sub freezing temps.

Fits well, doesn't move in jacket, very comfortable I got this back protector for my Dainese Avro jacket and it fits perfectly. It doesn't move around at all and on the bike I can't even feel it's there. I like the CE level 2 rating, and while it does not go as far as a separate back protector would, it is very nice for street use. Only ridden in cooler weather and the jacket it leather, but seems like it would flow plenty of air. Hopefully I won't need to test it's crash worthiness, but reading about the material and testing it seems like it will do the job and the price was very reasonable. March 25, 2014
Comfortable A+ Armor I replaced the foam back pad in my Joe Rocket Dark Radar Jacket with the Klim D30 Back Protector. I could not be happier with this product. Not only is it some of the best protection with CE2 rated armor, It is also a million times more comfortable than the firm foam board on my back! I would recommend this to anyone looking for great protection, comfort, and value. March 24, 2014
Great Add-On Armor I added this to my Harley-Davidson mesh jacket and it was too big to fit so I nylon tied it through the exisitng holes in the back protector to the inside of my mesh jacket and it has been long lasting now and looks factory even. This D30 armor is the best in my opinion. I have gone down on my elbow and shoulder piece on jagged gravel with it and I swear to God it was like falling on a memory-foam bed. Conforms to body... even in 17 deg F weather my body kept it warm enough to stay soft and pliable. No problems there. Note: Some back protectors are rated to EN-1621-2 Level 2 which means it can absorb/delay to 9 kN of force. You back is important... get good coverage and CE Level 2 for your back. March 10, 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

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

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

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

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 (0)
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
