RegSilk™ fibres stop bacteria from building up.

And refuses to reveal itself under tight pants.

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.

Review

Very happy with the bikini and the Glowtint bra but two comments - the packaging on the bra is way overdone - such a waste of resources. And the insert creases when the bra is washed - only a small point but it’s annoying to
have to ‘massage’ your bra back into shape before wearing !

Best Horseriding Knickers Ever

My sport is endurance riding (long-distance competitive horse riding). I have spent 30 years searching for these knickers. They don't rub, chafe, bunch up or slip down. I literally don't give them a thought from the moment I put them on. I bought one pair, trialled it, and immediately bought another four. They won't be the last!

Amazing & comfy

These are by far the most comfortable underwear, you feel like you are wearing nothing, no digging, so soft and breathable.

Size (AU): 10-12

Purchased size: M

How it fits: A bit loose

So Comfy

Very comfy and feel great on. Bought medium and whilst they fit nicely I potentially could have gone down to a small.

Size (AU): 6-8

Purchased size: S

How it fits: A bit loose

Love these. Can’t say they are invisible under garments but they are super comfortable, light and fit really well. Ordered quite a few pairs in various shades. They’re perfect worn under training gear or whenever you want a smooth silhouette.
