Michael Grobicki wrote a review of Patagonia R1 Hooded Fleece Pullover - Men's on January 8, 2012
I bought my R1 hoody about 3 years ago, yet it looks like I bought it just a few months ago. Wore it 75 days straight when I spent a summer in Alaska and it stood up to a massive amount of abuse in the form of bushwhacking, sea kayaking, and climbing. I pretty much never leave the house without it if I'm going hiking, climbing, snowboarding, etc. I'm ~ 6' tall, 150 lbs. and the medium fits me well. It definitely has a very athletic fit to it.
If you're looking for a lightweight fleece layer, then look no further.
