These are great everyday sweatpants although they run large relative to the size chart provided by Amazon. I purchased these for my somewhat picky 11 year old son. He gave them a thumbs down based on the style and wouldn't even try them on. I kept them because the price was great and I knew there'd come a day when he just wanted some soft fuzzy warm pants. Sure enough he wore them last weekend and loved how they felt but they are quite large on him. For grins I slipped them on today and to my surprise they fit me just like my Gap joggers. I am in love with these for myself! The boys large looks like a slim fit ankle jogger on me. I'm 5'7", 140 pounds, apple shaped with a 30.5" waist and slim legs.  He's 5.3", 105 pounds and normally wears a 12 slim. I'm going to get him a pair of medium and another pair of large for myself.

Update: The mediums fit my son perfectly. Use the size noted on the product name, not the size chart provided by amazon.
