So I hesitantly will be replacing my heavy knit wool sweater (18oz) with a new layer.

After much research I purchased the newest revision of the Patagonia R1 full zip fleece.

Seems like a very popular and beloved shirt.
I should have it in the next week just in time for a 3 day trip up into desolation wilderness in the Sierras; I do this trip every year with a couple of buddies and we have experienced temps in November ranging from 65 and sunny down to 0 with over 100 mph winds, we even got a couple feet of snow last year.
I will let y'all know what I think of it once I get it but until then I would love to hear experiences with this piece of gear if you care to share.
