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.
BioFlex™ Ultra Seamless Mid Brief
I wanted to like them, I really did. Put them on, they fit comfortably, light and stretchy. But despite the promises and the strip of silicon on the leg line around the rear, they very quickly made their way up my butt. If you want to make a pair of knickers that do not do this: rather than a silicone strip, actually cut the knickers sqaure at the rear instead of triangular. Who wants that anyway? Probably okay if you are a size 6.
I really wanted to love these. I have now worn them on two occasions, thinking maybe they rode up because I had body moisturiser on but today I put them on again with zero moisturiser and I have had to adjust them every time I bent over or stood up. Extremely frustrating. Buy the BioTracker with confidence. I do love how the gusset comes up a little higher in the front as most underwear it’s too short.
Really light and comfortable.
I LOVE paire undies usually and am a repeat shopper. I was really excited when the ultra seamless briefs were added as a product because good quality no-show briefs are so hard to find. I really like the fit and feel of these, but there is a grippy tape-like strip along the edge that i guess is supposed to be a hem and stop the undies from riding up while still being ‘seamless’. On two of the three pairs I bought, this edge tape came loose and began peeling away after only one wear. I noticed it was peeling away even before I put them through the wash. The third pair has since had the same issue, but after maybe 3-4 wears. I was so disappointed! Hopefully paire trouble shoots this, because otherwise they would be a great product
