I just received this jacket, which I ordered from Amazon. My intent was to find a jacket to wear in 30-40 degree weather, that provides high visibility. This is my first "cycling jacket" so I have a few questions:

1. This was listed as a men's jacket, but the zipper handle is on the left. Is that normal for a cycling jacket, or is this a women's jacket? (I've e-mailed the company, but it's the weekend, so no response back yet.)

2. I'm not sure whether I need a larger size or not. I'm able to wear a Russell Athletic Compression shirt (bottom layer), plus a Maser zippered (ski) turtleneck (cotton) under the jacket - but nothing else. I know that these style jackets need to be form-fitting, but I'm wondering whether I should exchange for the next size up, in order to fit another layer underneath, when necessary.

FWIW - My rides are generally 1 hour in length - 10-12 miles (hoping to increase that), so it's not as serious a cyclist as most of you here are. I plan on riding a few times/week in the winter as weather allows, just to stay somewhat in shape - in between the days that I go skiing. Of course, when warmer weather arrives, I'll increase the frequency and distance.

Any thoughts on whether to return (due to the zipper situation) or exchange the jacket for a larger size would be appreciated.
