BOOST™ Adjustable Absorbency

Protection you can customize

Absorbs 4-8 tampons

Not every day requires the same level of protection. That’s why we developed BOOST™, our adjustable absorbency system.

BOOST™ allows you to customize protection using a removable absorbent BOOSTER™, adding capacity only when you need it.

What is a BOOSTER™

A BOOSTER™ is a removable insert shaped like a pad without wings that is designed to fit into our BOOST™ underwear.

How it works

BOOST™ can be worn with or without a BOOSTER™ for light or heavy coverage.

Adjust absorbency by sliding the removable BOOSTER™ into the front and back openings of the gusset.

How it performs

BOOST™ features our integrated three layer leakproof system to wick fluid away from the body and absorb up to 4 tampons worth of fluid.

Why we made it

Adjustable absorbency means better comfort, better performance, and you need fewer products overall.

Made for Humans, By Humans

OEKO-TEX® certified

Our fabrics are certified free from harmful substances, gentler on skin, safer for long-term wear, ultimately, reducing irritation.

Stitched, not glued

Stitched seams hold up through 100+ washes. Bonded (glued) construction stretches out and breaks down over time.

PFAS-Safe*

No PFAS or unnecessary chemical treatments in our leakproof layers, materials designed to be safe against your skin.
