This is the Ninja Suit you wear to the grocery store. Single sided fleece is as cozy as it gets. Full front chest snaps add chill level street cred, and provide easy access should a passionate love find themselves unable to resist ripping these Underalls off of your body. And then probably eventually stealing them. Until then, enjoy your Underalls to the fullest. From the street to the summit to the bedroom, Underalls get'er done.
