Check out the local dealers for a sizing / try on. Dealers here have lots of em in stock. I did a search a while back for protective gear & found a site that tailor makes gear. They do a lot of work for police bikers & military. Sorry I don't have a link. But they use kevlar material that I believe they engineered.
Are you talking about
Motoport,
with their kevlar air-mesh equipment?
I bought the pants. They look and feel VERY durable.
They are quite bulky, though.
When I added the rain liners ($100), I could not ride with them at all. I put about 5 hours on them on one ride last fall, and felt claustrophobic, which I never do...
I asked about a refund, and they refused.
While the kevlar is probably about the best thing going for summertime protection, it has really impacted my enjoyment of the sport. It is frustrating.
