Well, you get what you pay for.  These have to be nearly the worst thing I've purchased on Amazon.  I gave 2 stars for fit and comfort, otherwise, definitely not worth the price.  After 2 washings, both pair ripped in various places and strings are dangling everywhere.  The rips did not occur along seams but in unexpected places.  The quality of these pants is just poor.  They are very thin cloth, which is not bad for sleep wear but the rate at which they are deteriorating is just unacceptable.  I cannot recommend these at all.

Update:  After about two months of use as sleep-wear, these pants are relegated to rag duty.  They pretty much dissolved with normal wear and washing.  Although they are inexpensive, it's too much to pay for rags.
