Okay thinking about getting one of these because they are inexpensive from ebay, and with a fleece they can be rather warm, suposedly. Does this look like a good candidate? http://cgi.ebay.com/COLD-WEATHER-CA...goryZ588QQssPageNameZWDVWQQrdZ1QQcmdZViewItem Thinking about a medium-regular because my chest is 38", and my height is 70 inches. Does the size they list account for room for layering fleece and other garments underneath? Or would I be better off getting a size larger? Here is the fleece: http://cgi.ebay.com/COLD-WEATHER-JA...goryZ588QQssPageNameZWDVWQQrdZ1QQcmdZViewItem Would this be warm enough for the winter in 20* farenheit or colder/warmer weather? its NOT for hiking or anything like that, as someone noted it is heavy. Mainly just for working outside, 4wheeling, and camping. Besides the fleece, would I need any more layers besides an insulated t-shirt or regular T shirt? Thanks...going to dig up my othe thread for reference.
