Q. What is Fresh Fix Technology®?

Fresh Fix Technology® is our built-in Panty Liner, available in several of our underwear silhouettes. It is moisture wicking, leak proof (on the sides and bottom), absorbent (up to 3 teaspoons) and anti-odor. It is roughly 2 mm thick and will feel slightly different than your regular underwear – because it is. Our Fresh Fix Technology® products are great for women who experience light bladder leaks, want back up protection during their period, wear panty-liners on a regular basis or are concerned about excess sweating or camel toe. It features our special one-way moisture wicking cotton as a top layer to help move moisture away from your skin and keep you dry. These are the ultimate leak proof underwear. 

To get our Fresh Fix Technolgy® Panty Liner, make sure to choose underwear with "Leak-Proof" in the title while shopping on our website.

Our non-leak proof (or regular) underwear feels exactly like your favorite pair of underwear but with a super power gusset. The gusset features a one-way moisture wicking cotton, that moves moisture away from your skin and keeps you feeling dry, as well as anti-odor properties.

 Q. What is the difference between your seamless underwear line and your athletic underwear line?

Our athletic underwear line (FitKnix®) is made of high performing LYCRA® FreshFX® fabric and the entire body of the underwear moisture wicking. It is also features LYCRA® Sport technology so it is designed to maximize freedom of movement, compression, stretch and recovery. It truly is a high performance panty. Our seamless underwear line (Knix®)is designed to feel light as air, like you aren’t wearing anything at all. It is made of a very light weight fabric and the technical properties are found in the gusset.

Q. Is your seamless underwear truly seamless?

Yes! We make incredible seamless underwear. Both our Knix® and FitKnix® lines are seamless and feature bonded technology (no stitching whatsoever) to ensure that our seams lie flat and stay in place. In fact, our underwear is so seamless that it has become a hit in the Equestrian community because it is invisible even under their super tight, white, riding pants.
