          Repeat Customer

          I’m a repeat customer. This order was to replace my original order from four years ago. Started getting a few holes developing but I’d never had underwear last that long thus a repeat order.

          Love the design! The boys stay in place and no pocket pool is necessary to get them back in alignment.

          I appreciate the quality and breathe-ability of the fabric.

          I’ll be back when I need to replace them again.

          What’s my size

          Well according to the size chart, it’s the above. The fit is more on the higher number of the scale. My waist size is 34” and less, so I should be covered, but they are bigger than I would prefer. To much room for error.
