Tryonic Feel 3.7 Back Protector

The Feel 3.7 back protector belongs to the top in its class; the outstanding balance between CE Level 2 impact absorption and wearer comfort due to its unique construction, lightweight components and ergonomic features are second to none. The patented Tryonic Vertebra joint system connects the polypropylene outer shells forming a rigid impenetrable shield and at the same time allowing for an unsurpassed freedom of movement. The EPS inner core ensures maximum energy absorption (< 4kN energy release), well within the CE Level 2 norm (< 9kN energy release). Another unique feature is the patented adjustable belt closure (T.C.F. Tryonic Custom Fit), ensuring a perfect fit for every rider.

The Feel 3.7 is also one of the most comfortable back protectors for high activity or hot weather riding due to the Coolmax mesh fabric in the back. As it performs up to minus 20 degrees Celsius, the Feel3.7 is the perfect choice for a variety of winter sports activities as well.


  • Outer shell from Coolmax stretch mesh fabric surrounded by thermoformed padding

  • CE Level 2 (3,7kN) – EN 1621-2 standard

MONEY WELL SPENT Luckily, I haven't had to try it's protection yet but i's extremely comfortable and I feel safe with it on. It's well made and I can't even tell I have it on. For bigger gutted guys, there is PLENTY of extra belly velcro adjustment. I'd make this purchase again and recommend it to anyone. My shoulders are much broader than what the measurements said but it still fits fine. I got a medium, for the back length measurement. I am 5'9 250lbs and it fit fine. December 1, 2014
Must have! Obviously any rider knows back protection is extremely important. This lightweight and extremely comfortable unit is just what you need. It might be on the pricier side for some but it is worth it. The only thing is I wish my bike had an easier way to store it. November 10, 2014
Awesime back protector I wanted this so bad and they didn't have in stock. Fortunately for me one came up and I got it as soon as I could. It is the white with blue in size M and it is great. Really confortable and hast a lot of room to adjust. I'm 1.75 hight and weight 190 pounds and it feats me perfectly. I was worried cause I saw one review that said the size M will not come with the elastic shoulder straps, this is NOT true. Mine is a size M and it has the adjustable shoulder " holders" and they fit correctly. I hope I never need to test it but is well built and it seems like its going to protect really well. My friend got a Dainese BAP protector and if you compare them side to side you can see a really huge gap in difference from the Tryonic Feel 3.7 Back Protector as it is superior in protection, style and confort. I WOULD REALLY RECOMMEND THIS TO ANYONE November 3, 2014
Good airflow and contours to body. I make it a point to wear gear whenever I ride just so I know I have a better chance of walking away if I were to ever get in a crash and there is no doubt in my mind that this piece will save me whenever it is needed the most. It contours to the body very nicely and even though my body heat is insanely high all of the time especially out here in Cali this back protector somehow keeps me cool. It is the best protector I have worn, and I have tested out a good amount of different protectors. Im not saying the others suck but this seems to fit my picky needs. Have a good one. September 22, 2014
Great product This is a great back protector. Fits very well, I am 178cm and bought a medium. I was concerned about ventilation, but the protector seems to be designed well. My only issue is with the two straps that go below the armpits - they are too tight or I have big lats, there is no adjustment for these so I just leave them open (might cut them out alltogether). But the protector is great overall, allows arching your back comfortably without feeling restricted. September 15, 2014
Beautiful piece I bought this for the track. A bit expensive but very well made. I already had a low side and it held up nicely. May 26, 2014
seems great This seems like good protection. It's my first back protector so I don't have anything to compare it to, but the high impact rating made my decision for me and I'm glad I have it. It's comfortable, I've had it on for a 4 hour ride and it didn't bother me at all. The only thing I don't like is the turtle-back I get with it under my Cortech Adrenaline jacket, but I would bet most good back protectors do this and protection is more important than style. The back protector on the outside looks pretty awesome, but you'll probably get a lot of questions too since you look like a power ranger or batman or something. I would definitely recommend this to friends and I hope I never have to use it. February 26, 2014
Great product What is protecting your back?? I had a smash at over 100k and broke back in 2 places as it was protected by foam.... I now ride feeling safer, if I had that same smash I would , hopefully, walk away wearing this..... Your choice, your back November 11, 2013

A shopper asked: Would the Tryonic feel 3.7 fit under the Rev'it stellar leather jacket? My stellar jacket is a size 50. I already have the seesoft back protector insert in my jacket but would rather have the extra protection this Tryonic provides... Also, would the bottom of it show?

Adolfo S: Sorry for the delayed response....I was away last week attending the Canadian National Superbike races.......

I wore my Tryonic Feel 3.7 Back Protector under my Revit Hunter racesuit and it is extremely comfortable, once on you dont notice it at all .....it doesn't need much room and the adjustable straps make it fit perfectly.
Not sure if it would poke out under a jacket but if so only minimally and for the added protection it offers,,,,its a no brainer. Highly recommend it.

hope this helps

Trevor B: I use the tryonic with an agv sport monza leather jacket. It is snug but it fits fine. Honestly, I would need to see your jacket on you. If there is an inch or two you should be good. Rev zilla will let you return it if you don't mark it, or take the tags off. Aug 17, 2013

Andrew C A: Hi there!
I only wear my Tryonic protector under my Joe Rocket 1 piece leathers, so I really don't know the answer to your question. It fits great with the leathers though!
Sorry I'm not much help to you!

Scott F asked: How thick is this compared to the Forcefield Pro Sub 4? I have the Forcefield now, and I'd like to get something a little thinner without sacrificing protection if possible. Mar 20, 2015
