The T-Pro Forcefield Back Protector Pro Sub 4 is the worlds first Motorcycle back protector to transmit less than 4kn when subjected to the standard CE test

The Pro Sub 4 has been specifically designed to test at under 4kn when subjected to the standard CE test EN1621-2. Independent testing by SATRA shows a mean test result of 3.38kn transmitted energy, making it the first motorcycle back protector in the world to attain this level of performance. Constructed with a removable and washable outer cover to give the rider the ability to keep the back protector clean and hygenic, it also makes the protector more flexible as it is not bonded at the edges, this in turn makes it more comfortable to wear, a prime consideration in the design process of any Forcefield product. As with all Forcefield Body Armour® the Pro Sub 4 has RPT (Repeat Performance Technology) ensuring continued and consistent protection even after multiple impacts. 

  • Removable and washable outer cover
  • CE Level 2 Rated Protection - (Highest Possible rating)

I purchased the Forcefield ProSub 4 based upon research. No one makes a back protector even close to meeting the standard Forcefield has achieved with The ProSub 4. The unit is light weigh and pliable, making a perfect choice for touring. Once the protector is on the the body heat from the back warms and conforms it to the body. If you wish to wear this particular protector under a touring jacket, then remember to go up one size in the jacket. Awesome technology and workmanship in an extraordinary well thought out product! Thanks!
Yes, I recommend this product.

I never ride without wearing the Pro Sub 4 back protector. It's very comfortable to wear because it conforms to the shape of your back after couple wears. I actually don't even know I'm wearing it sometime.

After much research, I decided to give the Pro Sub 4 back protector a try. From what I understood, many claimed that the protector is the best in its class for protection, lightweight, great quality, and very comfortable. Some reviewers would claim that they "didn't know it was there" after a short period of wearing it. They were right about everything except that it doesn't "disappear", but it is very comfortable to wear on or off the bike. Because of the bulk and the waist band, you will know it's there, but I never found it to be uncomfortable.
Quality and fit are great. It is very light and the dual strap waist bands are very functional for comfort. I do find the protector to ride up a bit when you're in full tuck, but it was not comfortable. Be certain that your leather jack fit can accommodate this back protector. If your suit or jacket is currently skin tight, it will probably not fit.
The weather has not been very hot (70F), so I cannot comment on the airflow, but it was perfectly fine during those temps. I can feel some airflow through the back protector, but I suspect it will still be a bit "warm" when I ride in Texas summer heat. Either way, if its the price for protection, I will pay it.
I was skeptical about the comfort of this kind of back protector, but I am now a believer. I wear this every time I am riding and do not regret the purchase at all. Since there is no other back protector to offer it's level of protection, it looks like it's the best in the market now. I would recommend this to anyone looking for the best no compromise back protector currently available.
Yes, I recommend this product.

From all the things i've heard about this protector it's the best there is from a protection standpoint. And isn't that what it's all about. So that being said i feel it's comfortable and flexable as well. Very light and fits under my suit well. Overall very satisfied hopefully will never have to use it but since it will take multiple impacts i won't have to buy another one. So eventhough it's pricey i feel it's worth it.

Bought the sub4 cause I'm an ER doc and have seen too many spinal fractures from motorcycle accidents. It clearly provides the best protection you can buy. Very light weight, easy to put on, fits snug. A little bulky under my jacket and the bottom stick out past the end of my jacket. I tried to tuck it into my pants but keeps popping out when I tuck. Should be ok if you zip your pants to your jacket. Ill tolerated it though cause it covers my entire spine.
Yes, I recommend this product.

Hi guys,

Looking at the Pro Sub 4, trying to determin the right size.
I am 5'11" or 6 foot depending on the day and the ruler, I am thin though which affects the waste straps. 34" waist. According to the size chart I would probably be at the edge of medium and the beginning of large. My instinct is to go for the longer large but I am concerned the straps will be too stout.
What do ya' think?

Thanks,
Adam

Answer: 
I am 6'2" and 210 pounds. I use the large ProSub4 and it is perfect. I would think that the medium might be better for your height and thin build as you described. My only reservation would be if you have a very long torso...in which case you might need the extra length of the large. The straps on the large also might give you too much material and be a bit sloppy under your suit. They gave a lot of material for a huge spectrum of torsos, which you don't need to worry about. Go Medium...and Revzilla is amazing at return/exchanges so you can't go wrong.

Answer: 
I'm 6'0" at around 195 with a waist around 36-37". I just got the large Sub 4. As far as fitting the length of my spine, it is perfect. But you are concerned about the waist strap. The strap is long, even for me, and I may have to someday have it shortened. With your smaller waist the large's waist strap will be way to big, try the medium, or modify the waist belt on the large.

Adam, I am 5'9" with a 33" waist and wear a medium. The protector fits well and I have plenty of room to adjust. I would think that you would still fit in a medium.

Answer: 
Adam,

I'm not sure if you made the decision yet, but I wear 36" waist pants and I just purchased the large. They are a little loose for my taste, so I'd recommend you go with the medium. If I had both side by side to try on, I probably would have purchased the medium.
