"versatile piece of clothing" - Review of Patagonia R1 Flash Fleece Pullover - Mens

I have been looking for a lightweight and warm technical middle-layer pullover, when I read many people raving about this R1 flash pullover from Patagonia. R1 is really a nice and versatile pullover: it's lightweight, non-bulky, warm for its weight (due to the waffle construction in the inside; the exterior is smooth though). I can use it as base layer during cold winter time (mind you though that your belly might feel the inside part of the zipper, as biger zipper is used compared to mini zipper in Patagonia Capilene products), or as a (outer) sweater for cooler summer night, or as middle layer during fall/autumn time. Really nice construction and quaility product from Patagonia.
