I bought one of the Sherpa lined ponchos over 2 years ago and it is still going strong. I got a size that would be a bit big on my then 18m old. We used it almost everyday for 2 cold weather seasons for daycare trips and outside time when it wasn't super cold. We now use it for our younger child.
It still looks great with no signs of wear. Also the pockets are awesome for storing gloves and small toys.
