Anyone who drops by the house and has seen me in my pajamas has to do a double take and ask me where I got them. Their second question is usually "Are they comfortable?" (yes, VERY comfortable) Third is usually "Oh my. Do you really use the drop seat?"POSITIVES:When I come in from an ice cold day, I slip out of my work clothes, take a nice hot shower and slip my "Big Feet" fleece pajamas on. They keep me warm all over and, heck, I've even saved a few bucks on heating!I was on the border between Medium and Large, but the sizing chart said I should get a large, which I did. When the pajamas came, I thought I had received the wrong size. Seeing that they were, in fact, a Large I slipped them on and was surprised to find out that they fit perfectly. They even have some built in space for when you are in bed and move around: there is no "restictive" feeling.They are also a great conversation piece: people think they are the coolest thing, they start to reminisce about their childhood days. The ladies also tend to think they are cute :)NEGATIVES:The fleece pajamas tend to generate A LOT of static, so if you're going to work on sensitive electronics in your pajamas (don't laugh, I've done it!), get a "Big Feet" pajama in another type of material.Also, the Velcro on the drop seat is VERY eager to stick to other parts of the pajamas, so be careful when you drop the seat and put it back or you might walk around the house exposing your unmentionables.In closing, these pajamas are a dream come true. I've been looking for them for quite a long time and I was glad to find out they exceeded my expectations.
