Troy Lee Designs BP 7850 Price: $115.00 from $105 on Amazon
My thoughts BEFORE using the Troy Lee Designs BP 7850: Before using the BP 7850 I was unsure of how much protection the all foam construction could offer. I was also worried about it being hot and uncomfortable.
My thoughts AFTER using the Troy Lee Designs BP 7850
Fit: Upon measuring my chest and looking at the size chart, it was obvious I needed a large. After receiving the BP 7850 and putting it on, I would say the large is a little too big. It fits kind of loose and with a product like this, I would expect a tighter fit. I didn’t get to try a medium, but my chest measurement was 3″ larger than the max for medium.
Comfort: Off the track the BP 7850 is very uncomfortable. On the track it isn’t super noticeable although it is a little warmer than wearing just a jersey. I believe if the ventilation and fit were improved, it would greatly improve the comfort. To increase comfort and airflow, you can also remove padding as desired.
Ventilation: Off the track the BP 7850 is very hot. On the track it is hot when compared to riding with no chest protector, but when compared to other under protectors (that offer much less protection) it isn’t too bad. It is definitely cooler than a protection jacket. The ventilation is decent for what the BP 7850 is, but it could easily be much better. There are two layers of foam, the vent holes in the layers don’t line up (enlarge picture to the right). If every hole did line up, this would easily increase the ventilation of the BP 7850 by 25%, I would guess much more.
Impact Protection: Troy Lee says “HEX-MESH disperses impact with a dimensional mesh construction that allows air to flow freely”. Hex mesh is the two layers of foam I talked about above. Basically, two layers of foam, the bottom softer and thicker, the top stiffer and thinner with holes in it for ventilation. Strata Foam is thick & softer than all other foam used and also has holes in it for ventilation. Strata foam is used where they need a foam that is very flexible for fit and comfort. As you’ll read in my crash test below, the BP 7850 offers good impact protection, especially considering how lightweight it is.
Neck brace integration: Removable padding makes the BP 7850 work very well with the Leatt GPX and Alpinestars BNS neck braces. Unfortunately even after removing the padding it would not work with my Atlas brace.
What I would like to see improved on the Troy Lee Designs BP 7850:
Removal: This thing is impossible to get off by yourself after a moto. It gets sweaty and its basically stuck to you. I even ripped it a little trying to pull it off once. The addition of a zipper for removal is a necessity.
Comfort & Fit: I grouped these two together because I believe if the fit was better it would be more comfortable. As I explained above according to the size chart I was easily a large, but the large is a little too loose. If it fit tighter to the body, there would be less moving around on the body and it would move better with the body.
Ventilation: The vent holes are added to both layers of foam before they are stuck together. Guess what? The holes don’t line up. Holes that don’t line up don’t vent. A simple way to make the BP 7850 vent better would be to stick the foam together then add the vent holes. This would improve the ventilation in a big way because all of the vent holes would line up perfectly instead of maybe half of them lining up.
Wondering how it looks under the jersey? Here are a few pictures of me wearing the BP 7850. I am wearing the same size jersey as I always do, as you can see the BP 7850 is basically unnoticeable under my jersey on the track.
My Crash Test: In the same crash where I tested the Kali Prana Carbon helmet and EVS RS8 knee braces, I tested the BP 7850. I typically would prefer to not crash hard and test items, but I did, so it’s convenient to use. The crash was 3rd gear over the bars and I’ve never had the wind knocked out of me so bad. I came out uninjured besides for a rib injury sustained right where I had removed some padding.
Final Thoughts: The Troy Lee Designs BP 7850 is a great option for someone looking for lightweight under the jersey protection that does more than just deflect roost. It could use some help with ventilation and removal, I hope TLD addresses these issues when they update the design.
