first let me say I only gave 4 stars because I have not washed the sweatshirt multiple times so I am not 100% sure on its longevity.  That being said, this is a well made WARM sweatshirt and is exactly what I wanted.  I was a little concerned about the synthetic lining but it seems to almost reflect back the heat.  I have plenty of technical gear for hiking that breathes and/or is waterproof.  This is NOT a hiking jacket but a great durable work outside jacket that you can unzip if you get too warm.  It is also my emergency jacket that I keep in my car here in the NE.  I also always keep a waterproof shell which I could throw over this sweat in an emergency.
