Living in the Sun Belt, for my part everything I own is either mid-weight horsehide or goatskin, all lined with incredibly durable cotton drill throughout. The only cold weather coat I have is a brown FQHH Teamster with moleskin body shell lining and cotton drill sleeves. The only jacket I own with a mouton collar is my USN G-l.^^Now that's a treat that will be waiting at your door!!
Just an offhand question for you, Butte, Nick, and many others -- how do you all in California manage to wear these jackets? Seems the season would be rather short...
