Core Technology
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 teardrop 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.
Orbit Weave
4D expansion
Aspire’s custom fabric composition and patented 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”
Modelling 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.

Initial Wear

Nearly Perfect
I love this underwear, but I do have some honest frustrations. First, the fabric stretches considerably over time. I actually started with M's and ended with XS's. The XS's were very tight at first, but after the initial adaptation, they fit almost perfectly. It wasn't that I was stretching them, th...
