Our CORE:TX™ Leakproof Bikini will be your ultimate everyday essential. With a flattering low-rise design and three absorbency levels—light, moderate, and heavy—it’s as functional as it is stylish. Soft, breathable, and leakproof, it’s here to keep you feeling confident no matter the day.

Mid-rise, moderate coverage with a waistband that rests below the natural waistline. Fits snug at first but conforms to your body with wash and wear.

Free standard shipping for orders over $50 CAD.
Within 30 days of delivery, you may return or exchange. The underwear item must be unworn, unwashed, and in its original condition with all tags and packaging intact.

CORE:TX™ System

3.0 features Razor-Thin Integrated Gusset for discrete and comfort even for everyday use.

5.0 and 9.0 underwear features Secure+ Floating Gusset for extra protection and provides a sleeve for disposable and reusable pads.

Other Brands

Other brands utilize common honeycomb fabric that absorbs liquid slowly, causing smears and overall dampness.

Sharp edges from machine-pressed glued edges harden over time and dig into your skin throughout the day.

CORE:TX™ Technical Fabrics

CORE:TX™ is our custom technical fabric that allows instant one-way liquid pass-through. Locks in liquid instantly to keep you feeling fresh and dry throughout the day.

Ultra-soft wrapped edges provides soft and smooth feel keeping you comfortable all day long.

CORE:TX™ 9.0 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.
