These have been great pajamas for my 83 year old dad who has Multiple Myeloma and has been fighting this cancer for almost four years now.  I have purchased eight pairs of these.  He wears these pajamas all of the time now, even to Dr. appointments most of the time.  He loves these because he calls them the good pajamas as they are heavy material and keep him warm.  I watch these all of the time and snatch them up when they go on sale.  The fit is perfect for him in the extra large although he also has some in the large size which he wears regularly as well.  He is cold all of the time and these are perfect for him winter and summer.
