cold weather & mesh kevlar
For those inquiring about stretch kevlar vs. mesh kevlar...
I own the Air Mesh Kevlar jacket and I ride year-round in Chicago. I haven't yet gone through the summer heat here in my mesh kevlar gear, but I have been out on harsh winter days. Here's a rough breakdown of my temperature tolerances in the mesh kevlar. I typically ride 45-60 minutes in this setup on an BMW 1150GS with standard windshield.
55 degrees on up - just the outer mesh kevlar shell
45 to 55 degrees - add the uninsulated liner
30ish to 45 degrees - add the insulated liner
25ish and below - I add my Gerbing electric jacket liner
45 and up - just the outer mesh kevlar shell
below 45 - add the uninsulated liner
below 15ish - I add long underwear
I'm something of a cold wimp, but I have never *ever* been cold on my bike in this gear. (I've been down to about 3 degrees fahrenheit, not including wind chill.) The electrics help when it's bitterly cold outside, of course. I wore an Aerostich Darien for two years and never got cold either. But I also couldn't bring myself to wear the Darien above 75 degrees which, in Chicago, is a huge portion of the year.
And my customer service with Wayne has been the single best customer service I've received from any company of any kind.
