RegSilk™ fibres stop bacteria from building up.

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.

So far, so comfy.

Bought these for hiking and my outdoors job because bamboo undies take forever to dry if they get wet. So far they're comfy and a nice cut. Yippee! I am usually a size 12-14 so I went for the bigger size and it's been grand.

Very comfortable but if you stuck with the bio-tracker thing they would be too expensive.

I've been wearing Paire for 3 months now. I wanted to wait for a while before giving an honest review. What I've noticed is that this is the most comfortable fabric to wear in very humid conditions (Far Northern Australia). I don't think I would find better. But - I've just received my second order, and I accidently ordered 2 full brief and 2 mid brief pairs. They appear to be exactly the same shape/height. Also, this is the annoying thing - the bio-tracker has already changed to pink/replace. These are premium items which should last a lot longer than 3 months. Who can afford to replace undies at $35 a piece every 3 months? I vote that they remove this bio-tracker thing!
I will continue to purchase because they are comfortable and good quality and last longer than 3 months.
(BTW, my usual size is 12-14 - the choices don't give me that option)
