This was ordered for my husband.  I followed the size chart and measured.  It was so tight he reminded me of a starfish in it  lol it was funny.  Good thing was we have a 16byear old that LOVES this kind of stuff and it fit her perfectly.  Other then the size this is a very warm soft sweat shirt.  She actually wore it in place of her northface because it had a hood and she said it was warmer.  As a product it is very good quality and holds up very well.  She actually shoveled snow (and even did the neighbors drive as well) and this was what she wore.  Gloves and hat too of course but as her coat.)  I would not think it would be good in side if it's that warm of a shirt she would always take it off as soon as she walked in the house.  Her other hoodies northface included she would often leave on until she got into her room.  So that should give you an idea how warm this is.
