Signs it's time to...

Size up

  • Waist sits more than 2 fingers below the belly button
  • Tabs barely close at the edges of the landing zone
  • Leaves lasting red marks or indents on the waist and thighs
  • You experience an increase in leaks, blowouts, and tears, especially overnight

Size down

  • Sags around the legs, leading to leaks
  • Gaps at the waist
  • Tabs close together or overlapping—tightening the waist to a point where the tabs overlap may “solve” waist gaps, but will cause leg holes to bunch and feel uncomfortable (like a belt that is too tight on big pants)
