This balaclava fleece keeps warm, and one thing I really like about it is it's extremely thin and compact so it's very portable.  I probably at times might rather be in a place where didn't need to wear balaclava to stay warm (lol, possibly), but I like how it's not some huge clunky bloated hat, fits in my camelback small pocket and yeah, suffices.  I considered rating this 4 stars simple because it's not spectacularly awesome, but there's nothing wrong with it and the thin-ness of it is definitely awesome.  I got the correct size, too (lg).  Fits really well.  Yah, I guess TL;DR not too excited about reviewing a balaclava, but for cold-weather cranium garment this is top-notch.
