Product Features

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.
