Size Guide

Unlike mummy bags, there is no thermal disadvantage to a larger size Zenbivy Bed because it is always free to wrap snugly around you. So bigger is always more comfortable and just as warm.  If you are an "active" sleeper or have a "wide" sleeping position, you may want to size up to sleep naturally.  When in doubt, size up.
