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.

I’m sold with the briefs. They feel really good on. I’ve talked my friends into buying your product as we’re travelling overseas next year.

Full briefs and g string

Very very comfy. My issue is I’m short and have a short torso so they sit really high on me and can be seen if I don’t wear shirts that are long.

Now all my undies are PAIRE

Its been a long journey to find one pair of undies to rule them all. I must have a distinctly 'hungry butt' as all undies creep throughout the day, causing great discomfort and an unattractive tick where I am puling undies out of butt all day long. The PAIR full briefs are PERFECT!!!! They snugly fit around the cheeks so stay in place all day long, but they dont dig in or leave marks when removed. They barely leave a pany line with leggings, and without bing too gross - they definitely smell fresher after a sweaty day of wear than my previous 100% Bamboo undies. Ive bought ALL my undies in PAIRE now and chucked out the rest. Im old enough that ALL my undies should be comfortable enough I can forget about them. SO happy I found them
