Great fleece with an inner polyester light sheet lining, I think it's almost like a fleece jacket, could be worn under a wind/water proof shell and you'd be proper toasty. Only selling because I didn't wear it that often. I''m 190lbs, 5'11" and it fits great, but I found it a bit too jacket-y rather than a mid-layer (under my shell). Just sat in my closet! I tend to use the patagonia retro-x fleece under my main shell layer. I think this is warmer and a bit bulkier than the retro-x fleece. I've seen this fleece listed for around $300 so you know it's a bit special and rare....and warm and stylish.
