The Voortex™

WELCOME GENTLEMEN

We didn’t construct the perfect pouch, we created the technology so that you can make your own. Our new aerated dual layered tear drop die casted Voortex™ is body-heat adaptive, and will form to accommodate you. Make yourself at home.

Hyprsonic™ WAVE

MADE BY SOUND?

An extraordinary material requires an extraordinary innovation to bond. We harness the power of audio by generating high frequency vibrations to fuse and reinforce our seamless structure. Imagine your entire wardrobe without a single strand of thread.

Welcome to the future of apparel.

MICROFEATHR™

ZERO-FEEL TECH

While maintaining the tensile strength and durability of a man-made fabric, Aspire’s proprietary surfacing technique conceives soft anti-pill micro-feathers that luminates and rests gently on your skin. Aspire is your balance of strength and sensitivity.

LIQUIFUSION™

TAILOR MADE

At 0.5mm of thinness, our patented waist & leg bands contain body heat reactive resin that sizes to your body. No more elastics or threads. Let’s minimize unnecessary deterioration.

    Love the new color

    I was skeptical at first when ordering my first zero brief but after a full day of wearing them, they are now the only underwear I use daily. They offer great support and feel like you’re wearing nothing. Order your correct size and give them a good stretch and a wash before wearing or they may be uncomfortable the first time.

    Wonderful

    As advertised, the briefs are like wearing nothing at all. The color is unique compared to any thing I else I have.. I like the thong style. Wonderful.

    Really like them

    Super comfortable and very different from any other underwear. Would love another pair.

    I am a waist 28-30 and got XS. They were tight at first but they form very well to all areas after the first wear and are very comfortable

    Love These !!!

    Very comfortable underwear. Each time these go on sale or bogo I have been ordering them. Definitely worth the money when they go on sale. We will see how they hold up in the long run but so far so good.

    Surprisingly comfortable

    I ordered a pair of zeros with no expectations and was surprised by the fit and support. I even ordered a few more in different colors. Love these.

    I'm liking these more and more.

    I have purchased all types of these. The thongs fit great. They don't feel like they are there. So far, the dominate styles prevent chafing. I still need to try it on a 10+ mile hike, but it used to happen even on 4 mile hikes. Sports briefs are nice to and I like how they really contour to your curves and accentuate the butt, even riding up a little bit. Looks pretty sexy.
