Our flannel boxers have a combination elastic-drawstring waist. The elastic is completely encased in flannel and not exposed to your skin.
Sizing
Hints for using this size chart. Instead of measuring yourself, it is easier to compare these measurements to a pair of lounge pants you find comfy. Lay your pants flat as shown in the pictures below. The flat waist, hip and thigh measurements will be approximately one half ( because you are measuring flat, not round) the values shown in our chart.
