I'm not familiar with the term "pressure suit." Can you tell me what you mean by that? Thanks.
I have a link in the blog to it. They are more commonly used in offroad riding. Its kind of like a mesh/spandex shirt with armor built in. This kind of armor is better because the guards really stay in place and provide great protection.
They are also better than just standard chest protection or roost-guards. Most of the chest pieces I have seen the last couple years zip up the middle, which creates a weak spot in the center of the chest.
A pressure suit is the way to go because all the armor is connected to it and held in place. The zippers are usually on the side, so there is no weak spot in the center of the armor. I wear a Thor, but there are lots of brands available that vary in armor type, comfort and fit.
