This is my go to armour that I've ridden DS offroad with for several years. It's extremely comfortable (cool when hot and warm when cool) and I don't feel the need to take it off when I'm standing around or eating lunch like I do my flack jacket. It's just that easy to wear - to the point where I dread my flak jacket. It's light, breathes very well and it pads you pretty much everywhere on your torso unlike flack jackets. It fits with my Leatt brace due to removable padding at the upper spine. I suppose it offers less protection in the most extreme circumstances, but I've crashed numerous times in this and never had an upper body injury. It's got kevlar on the elbow pads so it's as tough as you need IMHO. THe only thing I wish it had was a zipper for easier removal and maybe a velcro attached hardshell chest plate for those days when a little extra sharp impact (rocks and branches) protection would be comforting. THis jacket offers light puncture protection and adequate impact protection IMO. A must-have especially for those that adventure ride and tour where comfort is key.

I have tried a lot of armor and most are hard plastic that transfers the impact directly to your body, it is not comfortable because of the stiffness. The best gear that I have is the best because I don't know it's there like my Sidi SRS boots - TLD's armor is comfortable all day long, flows more air than seems possible and I have field tested it at speed - great product!

I wear it for hare scrambles. I've wrecked my bike with it on and my upper body was unscathed. My legs were covered in bruises. Love it.

good fit and very comfortable, doesn't constrict my movement at all, has decent airflow

I like this better than the crazy flak jackets under a jersey.

I've had the 7855 for a year now riding mostly woods single track on a dirt bike. I also wear a Leatt GPX 5.5 and a hydration pack. The Troy Lee shirt works extremely well with the neck brace as you can remove padding at the front and back so the brace sits close to your body. I wear the 7855 under a jersey with the Leatt over the top. Most days the shirt breathes well, especially when you are moving, but on the hottest days it can be a little warm. Some of the padding can be removed for better breathability but at the sacrifice of protection. Another great feature is having elbow guards that never slip down. My arms are slightly long for the size large but the elbow guards still stay in the right spot. I have thrown the whole shirt in a front load washing machine several times with all the armor left in and it has held up well. There is one spot on the side where the mesh holding in the padding is torn from a crash but it still works fine.

I tried a Leatt 3DF shirt which was surprisingly heavy compared to the Troy Lee and the Leatt felt like the armor would shift around compared to the Troy Lee. I also have a Leatt 5.5 HD that I never wear because I like the Troy Lee so much. Even though the Leatt neck brace should work well with the Leatt chest protector I was never able to make it work for me. The 5.5 HD feels very bulky and overkill and it made the neck brace feel like it was pushed up into my helmet making head movement difficult. Since I am woods riding most of the protection I am looking for is from tree branches and slower speed crashes; roost is not an issue. Next up I am trying an Alpinestars A-4 with Troy Lee elbow guards. Hopefully it will work and upgrade my protection but candidly it will be tough to beat the overall package of the Troy Lee 7855.

I was really impressed by the quality and fit. It is so slim and comfortable that you hardly notice on at all. Does not restrict movement in any range as far as I can tell. Has protection literally around the whole thing, even along the collar bone.
It was pricey but I think well worth it. If you're hard core, and want max protection, a hard shell one might be better but if your after good protection and comfort this would be hard to beat. I'm very happy with the purchase and Revzilla!

Good fit awesome in hot weather
