So, here in Austin, TX, we don't have much need for 800 fill, 20 ounce down jackets; but a light-weight, solidly built down vest? Sign me up! When the temps around Central Texas drop down into the 40's, I reach for this vest and I'm comfortable the whole day. I haven't been on any trips since I picked up this little bundle of excellence, but it has served me well at the office, in the field and on jaunts around town. And for those of you that think the Autumn Leaf color is a bit much? False. Like the bottom line says, wealthy and attractive women, cougars and cubs alike, are mysteriously drawn to me when I leave my Marmot Zeus jacket in the stable on those chilly days and dawn the Patagonia Down Sweater Vest of awesomeness.
