So comfy you’ll forget you’re wearing them

No seams, no tags, no constant readjusting

Naturally breathable fabric keeps things comfy and breezy

BioFlex™ bends the rules of conventional fabric. Made from 50% recycled corn waste, our bio-based material is created through an innovative process in which starch glucose is extracted from straw and regenerated into a nylon fibre.

The result? A durable fabric that’s lighter than air and soft as butter. Superior breathability and four-way stretch. A skin-hugging fit that’s moves with you.

Undies that ride, roll and bunch up are a thing of the past. Featuring no-slip silicone grippers on the leg-line and moulded grip zones, you can trust these undies to stay put.

VPL who? A seamless construction creates a smooth silhouette, while laser cut edges eliminate lines under clothing.

Thanks to a gusset made with RegSilk™, our material of regenerated silk cocoon protein fibres, these undies keep you fresh all day. Beat odour. Stop bacteria in its tracks.
