While you may use a two piece suit on the track, they are generally regarded as street gear.  The Fieldsheer Radar 2 Piece suit is a good example of a leather suit that contains some street oriented features.  Pockets.  It actually has pockets.  It's not as street oriented as a textile suit, but being primarily constructed of leather, it offers more protection.  The suit is also heavily perforated which makes it ideal for hot climates.  In a solid leather suit I'm comfortable down to 40 degrees F.  With the highly perforated Radar suit, my comfort level is 50 degrees F.  On really hot days, it's much nicer than solid leather. 

I only have three minor complaints with the suit.  One, the sizing of the suit is a bit odd.  For this test I weighed in at 220lbs, 6' 1" height, 48" chest, 36" waist and 34" inseam.  I went with the XL size or 46 according to the Fieldsheer sizing chart. According to the chart, 48-50 chest, 33-34 sleave, 40-42 waist and 32.5 inseam.  The waist on this suit is huge.  If I don't wear the jacket, the pants will not stay up.  There is also no way to cinch down the pants to fit my waist.  This is a suit for somebody with a big belly.  The chest on the suit is actually a bit snug, but not uncomfortably so.  The legs and arms a bit snug, but only as snug as they should be.  The rest of the suit fits wonderfully.  My second complaint is the zipper that attaches the jacket to the pants is a slight bit finicky.  It took me about 10 minutes the first time I tried to connect it.  But now that I'm used to it, I can get it connected right away.  Only occasionally do I not hold the zipper at the perfect angle to attache the two.  My third complaint is that the collar has a really large diameter.  It does not come anywhere near my neck.  It doesn't cause any problems, however I've had bugs fly straight into my leathers through the neck opening. 

The O'Neal Typhoon enduro jacket comes in any color you want as long as it's black. Yeah, I know, that was bad. But it's a good jacket. It's very durable and over the two plus years that I've been abusing it, it's taken it all in stride. It's not a water proof jacket exactly and it's not sold as one, but it keeps me dry in all but the worst down pours. The main weakness in it's weather proof defenses are the zip off sleaves. Water will leak in first around the seams at your shoulders and cuase water to leak down around your chest. I've never unzipped the sleaves. The jacket has enough ventilation and will stay securely in place when the front zippers are unzipped from the top and the bottom. This lets enough air in to keep you cool that I've never needed to unzip the sleaves. I also prefer to err on the side of being over protected.

Progrip makes some great stuff. I've used their off road goggles a lot. I particularly like the light sensitive goggles. I thought it might be a good idea to try their light sensitive add on lens for my streetbike helmet. I ordered one and installed it.

Superwool is a calcium-magnesium-silicate insulation material that is similar to fiberglass. Most fiberglass will melt at 700 degrees Celsius. Superwool is rated to 1300 degrees Celsius. Fiberglass also tends to shrink and become brittle at higher temperatures. Superwool is however not specifically designed for use in glass pack exhaust systems. Well, we'll see about that. I've decided to pack the exhaust can of my RC51 and see how it holds up. When working with superwool or even fiberglass it's a good idea to protect yourself from the fibers. They can scratch your eyes, and get embedded in the lining of your lungs. That can suck.
