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.

Tryonic Feel 3.7 Back Protector 4.8 5 17 17
Comforting and comfortable A back protector is an absolute necessity when riding, and this seems to be the best one out there right now. On top of the touted "3.7kN energy release," this thing offers near-total coverage, spanning my shoulder blades and covering my tailbone, even in the tuck. It's darned comfortable, too. I recently got another jacket that didn't come with a built-in back protector, and almost didn't bother ordering one to put in it because this standalone Tryonic one was so easy to wear underneath. Whether I'm in my regular gear or my race suit, I simply forget it's there. February 28, 2016
Best protector out there. Don't be cheap! Although I can't say if it works, because I haven't tested it and hope I never do! It fit under my suit, which I never thought I had any room to fit anything under! You don't even know it's there. I bought this protector because it is the best! I just watched my son last month, crash and fracture 3 vertebrae, he now has screws and rods in his back. He was wearing a protector, not this one. But he will be wearing one of these when he gets back on a bike August 17, 2015
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.

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
