I was loyal to the Patagonia equivalent of the TNF Windfall Vest for the last 5 years. I still wear it to this day. It's great quality, always looked new even after many washes etc.. but after a few years I figure it's time to get a new one, even though it still wears perfectly... so I got the TNF Windfall on sale here and I love it just as much.It's just as good if not better. It's an all occasion, all weather essentially windproof thin fleece vest. I wear it out with shorts, jeans, backpacking, it keeps me warm when worn over a wicker shirt, etc. I wear it hiking, backpacking, lounging, going to the store, etc...I got the mens small and it fits me perfectly (5'7", 154lbs, 40chest/31waist). Everyone needs one of these, they are just that all purpose useful. I'm not trying to sell anyone on it or a particular brand. I literally live in this as the post below states and stand by these windfall/windproof fleece type vests as really all purpose technical gear that looks great just wearing with jeans into the city too.
This is not winter gear but it is decent 3-season gear.
