My first string fleece
This is a great fleece: it's genuinely warm, it's fitted (due to the stretchy panels on the sides) yet night too tight, and it's durable. As soon as I tried this one I knew my other fleeces would be relegated to the second string.
I'm not sure this runs small, it's just a neater fit than a lot of fleeces. I'm 5'7'', 135 and usually wear a medium, and I wear a medium in this. If I had a quibble, it might be that it's a tiny bit short, but other than that the sizing has never been an issue. I would definitely buy this again.
