The Zonker can be worn in many ways. How you plan to wear it will influence your sizing decision. If you want to sleep in the Zonker with the bottom cinched closed and you are within 3 inches of the upper limit of the recommended height, we recommend you size up so that you have a comfortable amount of space for your feet. To walk around or lounge in a Zonker simply cinch the bottom of the Zonker around your waist and fold the extra material over.
