Purchased this for my son.  He already had one but used the first so much that he wanted another.  If you are outdoors in the harsh winter for whatever reason, this is a must have.  Especially if you have any health concerns like asthma.  There are breathing vents so no "closed in" feeling to it, plus it is a lightweight material.  Also can be washed up and hung up to dry.  Was not able to find in local sporting store this this was a great find!
