Upgraded the D30 T5 EVO X pads standard in the Klim product for increased protection.
D M on Jun 16, 2017
Great replacement for what was in the Joe Rocket jacket. Should be the standard and charge slightly more for the jacket to begin with!

I have D30 armor in a Klim suit, and find it to be very comfortable in use. Since this purchase, I've bought two more to install in other jackets.

Ben L on Jan 19, 2017
Klim has a name for providing the best quality
Eric F on Jan 14, 2017
Just slightly smaller than my Nucleon protector, with the same level of protection. It is also more comfortable for my jacket that is a little small in the chest
Jeremiah S on Dec 28, 2016
for my jacket extra protection
BULISTC on Dec 27, 2016
I have to protect my back.
Hien T on Dec 8, 2016
I choose this back protector to fit with the Klim Traverse Jacket.
R E on Nov 25, 2016
After visiting the retail location and speaking with one of the sales reps there. He explained that upgrading the back protector on jackets is a common thing to do. Who doesn't want to protect themselves?
Ross H on Nov 14, 2016
Great back protector, I had to cut to fit in my Rev'it jacket but it is super comfortable and the impact hardening of it is very impressive.
BURKE P on Nov 10, 2016
New jacket has D30 everywhere but the back.Now I have the full package.

my cortech jacket had foam for the back padding and I saw this and it fit my jacket and I didn't have to cut it to fit and it is breathable.
John T on Sep 27, 2016
always good to have back protector , especially if you fall
Henry L G on Sep 25, 2016
Molds to your body when warm. I put one in each of my jackets.
Kameran A on Sep 19, 2016
Recommended by Revzilla as replacement armor for jacket no longer in production.
Eugene W on Sep 19, 2016
d3o - cool tech. I like my bike gear to not look like bike gear - i.e. no massive shaped pads that restrict movement and make me look like I'm going into battle

troy s on Sep 8, 2017
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?
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.
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
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.
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.
Will this fit a Klim Altitude jacket?
donald n on Nov 21, 2016
BEST ANSWER: Yes... this material is made to be cut to fit and replace any armor.
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.
