Super-soft tree fibres

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. But nasty bacteria can build up on the undies that we use regularly, making them uncomfortable and unhygienic to wear

That’s why we’ve invented BioTracker — a smart paire of underwear that does the tracking for you. Designed with active proteins that sense external stimuli, this handy tracker changes colour with wear, so you can decide when it’s time for a refresh.

From skeptic to big fan!!

I find it difficult to find good fitting underwear. I wasn't sure i wanted to spend $25 on another probably disappointing pair(e) but id heard a lot of good things. The 100 day returns was a big seller for me and I'm pleased to say i won't need it. They aren't 100% perfect (but i do have a very... Unique shape) but they're the best pair of underwear I've bought in years, plus the odour capturing claims are true! I kept my usually sizing with underwear (I'm a 10 in skirts, 12-14 in pants and usually 14-16 in underwear so took a large and they are JUST large enough to contain the 🍑 without cutting in) I plan to only buy paire from now on, but will need to do some careful saving or strategy purchases. Worth it though

These knickers are lush. Soft, light, well fitting and almost like wearing at all. Very pleased with this purchase.

I bought one pair to trial for an upcoming trip. I was looking for underwear that I would be able to handwash and dry quickly. These did well on the trial run at home so I will be buying more to complete my quick dry travel wardrobe. I normally wear 12/14 Bonds and the medium fit well. The large size fit well too but I prefer them a bit more snug, so medium Paire it is.
