Super-soft tree fibres

Powered by NudeTech™. Feels like a second skin.

Anti-smell & antimicrobial

RegSilk™ fibres stop bacteria from building up.

Never sweaty, always breezy

And refuses to reveal itself under tight pants. 

Brown

This is not your ordinary brief. Made with fancy things like our sustainable silk and signature squat-proof technology. So you can feel things like the perfect amount of stretch, without ever sagging, bending, or snapping. 

Our trademarked NudeTech™ gives your briefs that special touch. Made from plant-based Modal, it’s what makes them feel like a second skin—like you’re wearing nothing at all.

Made with RegSilk™—our regenerated silk cocoon protein fibres—which has antibacterial and anti-smell properties to keep your most sensitive bits happy and to stop bacteria from building up. The world’s first Pilates-proof panties. Thrush? Don’t know her. 

Not sure how old your underwear is?

With busy lives and schedules, most of us aren’t keeping tabs on when we last spruced up our drawers. So consider these undies your reminder app — their handy tracker changes colour with wear and time so you can see how long they’ve been in rotation for.

Designed with active proteins that sense external stimuli, BioTracker™ lets you decide when it’s time for a refresh.

Comfy undies

Mid rise sits on me at belly button level, which is great for me. Super comfortable, light weight, sits nicely and stays in place. No roll down.
Colours are lovely.
