Dainese Thorax Chest Protector 4.6 5 9 9
Level 2 protection This is a very beefy level 2 chest protector which is used up to pro level racing. As Dainese literature states, level 2 is for maximum protection with less comfort, level 1 is less protection with more comfort so you must decide which is best for you. The protector is very well made and is thick and stiff. I wear it in my Frazer air summer jacket, which has a built in pocket for a protector. It works for me, but a thinner, slightly smaller, level 1 protector might be a more comfortable option for some. For me, I want the most protection I can get. I feel the size chart Revzilla has posted could use some tweaking. I purchased a smaller size than was recommended for my jacket size as I'm at the smaller end of my size range for the protector, so went smaller and it worked out perfectly. March 12, 2014
Does what it says on the tin... I hope The thorax protector seems like a good solid piece of armour. It's thicker than I thought it would be and covers most of my chest and certainly gives the impression that it will be an excellent layer of protection should I ever have need for it. At first it seemed a little big, but actually it's very easy and quick to fit - just slot it into the left side of the chest, zip up, and it quite comfortably stays in place when riding. Air flow seems very good, but it doesn't get very hot here. February 11, 2013
Simple and great I have not "tested" it and I hope I never have to but if I do crash, this will save my chest. Simple to put in the jacket and not too noticeable when you are wearing it. I Recommend. January 21, 2013
Slight mistake I purchased the Thorax Protector with the Dianese Racing Leather jacket thinking the jacket had the Thorax pocket. This was my mistake for not paying close attention to the features. Not wanting to return the product I modified my jacket to fit the Thorax protector. After the modification everything still first fine, it's a comfortable piece, the protector doesn't shift while I'm riding, and I gained just that much more protection. Even though I made a mistake I'm a little pleased I did. I have a little more protection than I did before at very little added cost. July 18, 2012
Protection and airflow. Been using this for a few weeks now. Pretty easy to throw into the chest pocket of an applicable dainese jacket, zip up and ride. Then remove and throw in a bag when you get off. I got the large, am about 6'3" 250. Have a 58 dainese jacket. The best part about the piece. Its just wide enough for me that if i slightly bring my arms together while riding it can pull the protector far enough away from my chest that a ton of air flows right through the non perf jacket. Really the best part by far. Actually makes me not want to ride without it. The protection is an added bonus. It also makes my soft pansy chest look ripped. Thats cool too. May 8, 2012
not suitable for street riding I bought this for added chest protection with my Dainese jacket and did not like the product at all because it isn't actually supposed to fit fully in the jacket pocket and isn't fully secured, which makes the jacket really hard to zip up too. I talked to a rep at Revzilla and they said this was better suited for track days, and I would agree that it is no doubt a heavily protective product, but Dainese did a poor job in designing these for everyday use and you will most likely leave these at home most of the time, so I returned it. If you have a Dainese jacket, I'd recommend going for an armored shirt instead if you really want the chest protection. April 6, 2012
For a few bucks more, u can save yourself the injuries.. Every protection goes a long way! This def. helps! February 21, 2012
A very nice size. Covers a very large portion of chest. Using in my Dianese Alien leather. Have not used in warm weather yet so not sure on air flow Very nice size. Covers a very large portion of chest. Using in my Dianese Alien leather. Have not used in warm weather yet so not sure on air flow. Will protect heart, lungs etc. if you fall. Would definitely recommend. January 23, 2012

RevZilla Store asked: Why did you choose this?
Eddie M: Great chest protector from Dainese to go with my Dainese Super Speed leather and textile jackets. Mar 13, 2014
C U: initially tried the the alpinestars track jacket for back and chest protector...the back protecton on that is flimsy and the chest is soft and although the coverage is broader, just from my own inspection, you would definitely feel impacts more and this protector is more designed to protect you where you would get hit more often particularly the thorax/sternum area..just makes sense..will try and see how it goes Feb 22, 2014
Thomas J: To protect my chest... why else would I purchase a chest protector? Dec 30, 2013

Lawrence K: The padding at the edge is about 1/4" The moulded plastic area is about 1//2". I have a medium. My chest is 42". The chest protector is a little bit flat for my chest . I hold it on with the main strap of the Dainese back protector and then a dirt track leather jacket. I also have Dainese elbow and knee guards. They all work very well. The only change I made was to replace the middle strap of the knee guard with a leather strap with D rings. The elastic strap did not hold it up on my leg. I have hit the grourd a few times, no injury at all.

William W C: I would estimate the thickness to be between 3/4" to 1.0" thick. It is very well
ventilated with many openings. It is also very lightweight; and once fitted properly inside your Dainese jacket, you will forget that it's there.

Patrick C: Its probably about 3/4ths of an inch to a full inch thick with spongy material on the side that touches your chest Jul 16, 2014

Brad K: With padding it's about an inch, maybe a little less. Definitely makes the jacket tighter. May 22, 2014

Eduardo R asked: Could I fit a size L on a size 54 avro leather jacket? I have a broad chest and shoulders and was told by some people to get an L. Mar 30, 2014

dan p: Yes the protector will fit. If your wearing a 54 you are in shape but probably not a giant person. The large is big and will fit people wearing 56-60 + size jacket. I have a muscular chest and shoulders and wear a sizes 65 jacket, but I purchased a size medium, but I tried on a large at a local store and it was very wide and dug into my shoulders when I was in the riding position. But get what ever size you want! Mar 30, 2014

A shopper asked: how does this work... a single plate goes in the jacket? My Alpinestars jacket has two chest pads, left and right. So how is this installed?

Maybe I'm misunderstanding and I have to order two of these for the Alien jacket?

hq227: Yes it is a single plate and sits partially in the pocket for it (there is only a pocket for it on one side and the other side sits free, but is secure when you zip up the jacket). So you would only need to buy one of these. Apr 6, 2012

Stevan P: This is designed as a single piece protector. It will fit in both pockets as you zip up the jacket and you only need to order one. Jul 14, 2011

Chris K: Dainese's size chart is a bit less helpful for protectors, however, based on my experience, you would be a size MD. Hope this helps! Aug 17, 2011

MICHAEL M: Don't know about its certification but how would you certify a chest protector. It's not like the company will guarantee your complete safety with this. Yes it fits inside a Ducati jacket and a Ducati race suit. I would imagine anyone traveling at hi speeds on a race track would have this and more. You simply can never be safe enough. It's a good product rest assured I have bought a lot of Dainese products and the quality is just superb. Nov 22, 2013

Lawrence K: I don't know about the pocket in that jacket. I use this chest protector and just hold it in place with the large wrap around on the dainese back protector. It's all under heavy leather jacket.
