I think for what you are getting it is quite expensive. the mouth piece is very large and difficult to thread through the camelbak to get into position. Also difficult to remove the cap with ski gloves on. i found the tubing very long, but then i am very short so that could just be my problem. Overall the insulation does work well if you are out in the cold weather. Its a great idea but over prices for what it is.
