I ordered a Gerbing jacket from A&S cuz they had them in stock. Talked to Kimberly on the phone first, then input my order on their website. It asked for arm length and chest measurements. They sent me a jacket that matched those measurements. However, it was waaaay too small, and the card on the sleeve confirmed that for a 46" measured chest, a size 50 jacket is what you need. Why didn't A&S know this? Also, I asked if it came with a BMW plug and she said "yes". I didn't. I called A&S and they fairly quickly (not as quickly as the first time) fulfilled my order with a size 50 jacket which I got today. And the appropriate adapter with a BMW plug for an additional $19. I tried it on tonight and it warmed gently...not as fast as my Widder vest, but nice down the arms. Did not roadtest it. I will tomorrow. It seems to fit okay, but it's tight in the neck. I'll either just deal with it, or I'll leave it unzipped at the neck and use my aerostich fleece neckthing (tm). Now for a question: With a Darien, where do you put the portable heatroller? I was thinking of velcroing to my left thigh, which would serve as a reminder to not o-shen my bike.
