The First Gear stuff is great, also.
The reason I'm a fan of Aerostich is that I've worn my jacket in comfort (as comfortable as one can get) in over 100 degree temps while riding through southern Colorado and northern New Mexico in August. When you open up the large vents under the arms, across the back, and run the front zipper down to mid chest, the jacket fills up with forced ventilation.
And that same jacket has been on my Polaris 600 Classic for an evening of bar hopping on the snowmobile.
And an electric vest is always your friend when it's cool or damp out.
Nothing's going to cover all faces of weather, but I've owned just about everything out there, and I always go back to my Aerostich Darien. The rest get put on eBay.. That said, I bought my Darien on eBay (used) over 7 years ago, and it's still going strong after well over 100,000 miles of abuse.
Abuse like being attacked by a Hodag.

And the jacket's been with me longer than my last 2 BMW's, V Strom, KLR, and 2 Gold Wings.. (and longer than the fiance)
