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.

4D expansion

Aspire’s custom fabric composition and proprietary weave pattern breaks the boundary of the last dimension. True freedom has arrived. You have to experience this. (actual photo*)

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.

TRUMOTION™

“LIKE YOU'RE NUDE”

Modeling the element of water, Aspire’s remarkable strength to support you whilst staying true to your natural movement is its unique characteristic. Go ahead, and ”wobble“ as you walk.

    Most comfort

    I was skeptical at first of how thin these were, I was definitely wrong. These are the best, most comfortable underwear I have bought!

    Almost 5 stars

    I love the fabric feel and breathability on my skin. I don’t know about the long-term durability, because i’ve only worn my piece a few times. For the cut, I’d like just a little less fabric on the booty edge, and around the hips, and a little in the crotch. I love the black because it hides stains, but I would love to see some bold colors in this same material and style.

    Comfort!

    Fabric is peculiar… in a good way. Incredibly thin and takes up the space of a tissue in your suitcase. Looks and feels sexy.
