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.

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.

Great Product

Comfortable and stays in place.

Very comfy

Extremely comfy and don’t ride …. Lipstick pants dry in 60 seconds with hair dryer

Disappointed after reading all the rave reviews. The material feels lovely, and they are a good height (more of a full brief than mid- I’m only 5’2”) however the bands around the top and leg holes cut in, so no smooth lines under clothing. They are more like a boy leg style than brief. For the cost i was hoping for far better!! Wouldn’t buy again.

Most comfortable knickers ever!

To be honest when I was researching this brand, I really wondered how many of the reviews were from real people and not bots. I was also concerned about the comments that mentioned fit (there were so many variations for the same size) that it took me a long time to actually purchase them.
In the end, I thought I’d take a punt and place an order. I’m an older Australian who is a rounded size 14 but based on my analysis of feedback I decided to choose S/M and they are perfect. They hug my bum, don’t rid up, sit just below my belly button and are oh so comfortable to wear.
Thought they might be too hot in our Queensland climate but they’re not.
I’m heading off overseas so bought 4 pairs from Paires and that will be the only knickers I’ll need to take with me.
The only thing you got wron is that this review asks if I got size S or M - they actually come in S/M or L/XL so that’s a bit silly and just confuses your customers.
That said, if you keep selling these knickers, I’ll certainly be buying them again in the future. Winning! 🥂

Size (AU): 10-12

Purchased size: M

How it fits: True to size

Comfortable and no lines

Nice fabric, easy to wear, pretty much invisible under clothes. Over priced if outside of the 4 for 2
