I wear one of several Eddie Bauer fleece pull overs almost every day from October to June in the PNW. I lost a 7 year old fleece (my green one, sob) on a flight back from Turkey and felt like I'd lost an old friend.

Work surplussed some heavy duty fleece zip ups, I snagged 4 and keep them in the trunk of my car for folks who come out of a fire with nothing to keep them warm. I think I still have 2.

Recommend windproof fleece for preparedness kits, its a darn sight warmer if the cold wind doesn't cut through, but anything is better than nothing.
