Fit Tips:

If your body measurements fall on the borderline between two sizes, we recommend sizing up for a more comfortable fit. If your hip and waist measurements suggest different sizes, choose the size that matches your larger measurement.

How to Measure:

Bust Place the measuring tape around the fullest part of your bust.

Waist Stand up straight and place the measuring tape around your natural waist.

Hips Measure around the fullest part of your hips.

Inseam Measure from the crotch seam down to the hem of the pants.

Worry-Free Backup

Sustainable

Razor-Thin Liquid Shield.

Razor-thin, and unimaginably over engineered, CORE:TX™ Leakproof System keeps you confident and comfortable all day long.

CORE:TX™ 3.0 shown.

360 Liquid Barrier.

Utilizing advanced water-proof stitching techniques and wrapped edges, the 360 Liquid Barrier provides double the leakproof performance while staying soft and comfortable.

RINSE. WASH. REPEAT.

Caring for your CORE:TX™ is simple. Quick rinse with cold water to remove any stains. Machine wash cold on a gentle cycle. Air dry to ensure longevity.

Reality Check.

Single-use products use over one million litres of water for production and generates over one million tons of waste each year. This waste can stay in landfills for up to 800 years.

Our commitment to the environment.

Caring for the environment is a responsibility we all share. Our biodegradable packaging ensures that once it’s done protecting your underwear, it returns to the earth without leaving a lasting footprint.
