I recently returned from Asia and was able to score a bunch of legitimate Arcteryx Konseal Pullovers for dirt cheap. After giving out a bunch to my friends and family, I have a few extra in men's medium and large. These are all brand new with tags, in original bags even! These are very similar to the Patagonia R1

From Arcteryx:

"A versatile piece for alpinists and climbers, the Konseal Zip Neck performs as a mid layer or standalone piece. Made from air permeable Polartec® Power Dry® fleece with a voided grid construction, it delivers a high warmth to weight ratio and has a smooth outer surface that helps wick and dry moisture and layers easily under a shell. The articulated trim fit moves with the body, the high collar provides warmth, and a deep front quickly ventilates excess heat."

These retail for $139, I'll be happy to sell them for $100 shipped.
