I love these pants.  I wear them all the time.
They are soft and durable and very comfortable.
Yes, they are thin -- and I want that in sleepwear
-- and yet they are durable.  They machine wash
and dry just fine -- I don't see any of this
rumored pilling.  I have not noticed any shrinkage.
I like the navy blue color.
My experience with the pair I bought is uniformly
positive.  I just bought another pair.
