QC Checklist

  • ✓Check the waistband elastic for even tension and no rolling
  • ✓Inspect the fly stitching for reinforcement
  • ✓Verify the fabric is breathable and not overly synthetic
  • ✓Look for flatlock seams to avoid skin irritation

Sizing Guide

Underwear should fit snugly but not compress. Check the waist measurement on the chart and match it to your natural waist (not your pants size). For trunks, the leg opening circumference matters if you have larger thighs.
