Another brand that is recommended is the Weatherby weatherproof wool series. The 2004 production is made of a thicker wool fiber that appears to be quite a bit stiffer than that of the 2003 production line. Personally, I was able to locate some leftover 2003 line that was considerably cheaper than that newer stuff. For example, Parka $229 (Cabela's) - I got mine for $129 (Reed's) on closeout...
Hope that this helps,
