I love this jacket- I have two of them.  The best feature is the 'windstopper', which prevents the wind from blowing through the jacket, especially through to the arms.  This jacket is hands down, night and day, better than the ubiquitous North Face Denali fleece.  I mention the North Face fleece because anywhere you turn, somebody is wearing one.  However, having owned both MH and NF, the Mountain Hardwear is the better jacket.  It fits better, has better pockets and most importantly, keeps the cold air from blowing through.  And should you find yourself getting too warm while wearing the jacket, simply unzip the underarm vent zippers and you are good to go.
