I have bought two sets of these sheets now.  They start out very silky (slippery), but some of that fades after a few washings.  Which I like.  I didn't want them to be as slippery as silk sheets.  But they are so comfortable!  Even my husband has commented on how much he likes them, and he rarely notices things like that.  And so far, after multiple washings, I haven't notice any pilling.
