I ordered this full breathable suit from Motoport a couple of months ago, and it had the chance to put it to the test on a 95º day today.
The suit is made from a heavy duty kevlar web that is completely breathable, which I confess I was a little skeptical about before it arrived, but honestly it really does feels like you're riding in shorts and a tee shirt, yet you have the best protection that you can on the road. After just a day in the saddle I am an absolute believer, and can recommend the suit to anyone.
It is made really well, and it is made in California, two big pluses. The only minus is you won't be winning any beauty competitions in it, but for comfort, practicality it is by far and away the best suit I've ever tried, especially for hot weather. The jacket and pants both have very high tech warm liners for when the weather cools off too, so if you live in a mostly warm climate, as we do here in CA, it is a real winner.
The entire suit, liners, maximum body armor, Scothbrite stripes and all was $1700 delivered.
