I finally found the perfect pajamas (for me, anyway)!  Lightweight, cool, comfortable & just the right size.  Already, the temperatures have been 100 degrees the past few days, & these are exactly what I've been looking for.  I bought the lighter color in XS...wore only one so far, & have washed, but don't know yet if there's any shrinkage.  I may order small next time if they did.  I plan to buy every color.  I absolutely love these!
