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.

    I love the fabric. Smooth as silk. Sometimes there’s a gap on the sides in front. Overall love them.

    Comfortable

    I really like this thong. I’ve been wearing thongs for close to two years now multiple times a week if not daily. These definitely disappear under your clothing and are very comfortable. I’m a larger guy with not the most chiseled mid section (working on that). The waste band on these roll really bad which I’m not a fan of. If I reposition them when my shorts are on I can get away with them not rolling. Assuming if I lose weight these would roll less. The package area could be wider to cover my crotch. They are loose on the left and right side of my package where the leg meets. Overall really good though. When I drop weight these will definitely be my go to’s.
