      though it really doesn't matter. Most of us can open a sleeping bag with either hand to start with.

      If you are right handed, you would want the zipper on the left side.

      This sleeping bag will comfortably fit a person who is 6' tall. It will be compatible with a women's bag as long as there is a right side zipper and a left side zipper. Campmor offers a one-year return policy.

      The Aleutian will zip to the Aleutian women's, just make sure you have the alternate side zipper. If you the Aleutian is a R the women's needs to be a L.
