DryGuard size chart and fit guide

Sizing is the one thing worth two minutes before you order — a pair that fits properly is what keeps the core sitting where the leak happens. Measure your waist, read it off the chart, size up if you are between.

Size chart (inches and centimetres)

Measure your natural waist — the narrowest point, usually just above the belly button — and your hips at the fullest point. If the two land on different sizes, go with the hip measurement.

How to measure in 30 seconds

A soft tape measure is ideal; a piece of string and a ruler works too.

  • Stand relaxed — do not hold your stomach in, you will size down by accident
  • Wrap the tape around your natural waist, snug but not tight
  • Note the number, then measure your hips at the fullest point
  • Match to the chart; if you fall between two rows, choose the larger

Between sizes? Size up

Our waistband is bonded flat so it will not roll or dig under fitted clothes — the trade-off is that it does not stretch to rescue a size that was too small. A slightly roomier pair keeps the core centred and stays comfortable through a full day of sitting.

This is the single most common reason for a first-order exchange, and it is entirely avoidable with a tape measure.

Fit notes by body shape

Small adjustments that make a noticeable difference.

  • Postpartum: size up while your body is still changing — you can exchange down later, free
  • Curvier hips than waist: always follow the hip measurement
  • Between L and XL and mostly seated at work: XL is the more comfortable choice
  • Wearing under leggings: true size gives the flattest line; the 3 mm core is invisible either way

What women say after 30 days

I stopped planning my day around the bathroom

After my hysterectomy I leaked every time I coughed. Pads shifted and smelled. My first DryGuard pair held through a two-hour walk and I honestly cried a little. I've worn nothing else for four months.

Nobody can tell — that was the whole point

They look and feel like regular briefs under leggings. No crinkle, no bulk, no smell. My daughter borrowed a pair postpartum and immediately ordered her own.
Denise R., 58Sarasota, FL · Verified buyer

Saved me about £40 a month on pads

I washed the first set over 60 times and they still hold. It paid for itself in the second month. Ordered the 10 pair so I never have to think about laundry day again.
