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.

Only one regret

I hesitated for a long time before placing my first order. I wasn’t sure about the quality of the products. I thought the price was rather high and I was a little confused by the different materials and styles. I finally decided to give a try. My goodness! It’s exactly the type of underwear I’ve a...

Love the booty shorts!

Even dudes need booty shorts sometimes. They fit just right, show off the goods, and don’t weirdly ride up. 10/10.

A Sculptured Fit

Adding to my AsWeMove Collection, I purchased three pairs from the Aspire Collection. The fit of the Aspire trunks is like putting on a layer of _____ (insert underwear color) paint on your body. You cannot tell you have them on but when you look in the mirror - you know you have Aspire on.

Solid top and bottom

The reason I like this model best is there an elastic band at the waist and on the bottom edge keeping the trunk in place. no creep.

Like wearing nothing

I had my doubts when they came. I wondered if I should have ordered a size up, but when I put them on, they expanded to meet the needs of my everything! I've already ordered three more pairs-each a different style, and I'll be ordering more before getting rid of my other sub-par undies!
