Endurance Junkie wrote a review of Patagonia R2 Vest - Men's on October 15, 2007
After a year of owning the older version, I realized it was the one piece of clothing I never leave home when I head into the alpine. So, when the new version was on sale, I had to try it out. Compared to the older, furrier version, the new R2 seems sleeker, more compact, easier to layer, but perhaps a tad less warm. I've found this to be a good tradeoff.
This little vest provides an amazing amount of warmth, yet lets your arms and pits sweat. Its loft provides warmth and allows it to breath amazing well. It also seems impervious to retaining any water and dries immediately. I own another Patagonia fur-type fleece and have found them to provide greater warmth for their weight than any traditional fleece. Additionally, as with all of Patagonia's technical clothing, its cut trim and slim for active, fit people using it as intended - in the alpine and backcountry.
