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 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”

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.

    like wearing nothing at all (a la ned flanders)

    love how cozy and smooth these are on the bod. the only thing that would make this brand better is if they had a jockstrap! (non-thong, though). would buy so many of those

    Nicholae, thanks for the 5-star review and the Ned Flanders reference — that "like wearing nothing at all" feel is exactly what the Aspire Sport Brief is designed to deliver! We're really glad that cozy, smooth comfort is hitting the mark for you. And we love the jockstrap suggestion — that's actually something we hear from time to time, and it's great feedback for our product team to consider. A non-thong jock with the same Aspire tech would definitely be an interesting addition to the lineup.

    Best underwear ever!

    I wear majority of tighter fitting joggers and pants and have problems with underwear lines. Then when I found AsWeMove and gave them a shot, it’s the only underwear brand I wear now. No underwear lines and feels like you’re wearing nothing! The zero (thong) line is amazing too as it feels comfortable and doesn’t give that wedgie feeling ever so you can wear it for the entire day. I highly recommend this brand! Sometimes I’m too lazy to handwash and hang dry them so I’ve been machine washing and tumble drying them for 2 years now and they still look and feel brand new.

    Hieu, thanks for the incredible 5-star review! We're absolutely thrilled that AsWeMove has become your go-to brand — there's nothing better than hearing that we've solved those pesky underwear line issues while delivering that "wearing nothing" comfort you're looking for. It's awesome that you've discovered both the Sport Brief and the Zero line and that they're both hitting the mark for all-day wear without any of those annoying wedgie problems. And honestly, we love that real-world durability test you've been running — 2 years of machine washing and tumble drying and they still look and feel brand new? That's exactly the kind of lasting quality we engineer into every piece. Thanks for taking the time to share such detailed feedback and for recommending the brand — reviews like yours really help other customers understand what makes AsWeMove different! 🙌

    very comfortable

    this underwear is very comfortable. it is a little bit tight for a couple minutes after putting it on but it really forms to your body. it’s pretty revealing, can really see a very very detailed outline of your privates, but it’s so comfortable it feels like you’re not wearing anything while holding your junk all in place.

    Innovation

    These are the most innovative and comfortable underwear that I have ever had. Fits like it is sprayed on. The detailing is quite incredible.

    Nice, Small to size

    Would recommend buying but sizing up if you are an athletic build. My first order left a very bad underwear line. Otherwise the material is nice and lightweight and I expect it to last

    Thanks for taking the time to share your thoughts! We’re really glad you’re enjoying the lightweight feel and durability of the Aspire Sport Brief. 🙌 Aspires use our heat-adaptive Stealthskyn™ fabric with Liquifusion™ waist and leg bands — a super-thin, body-heat reactive resin that molds to you without traditional elastic. That seamless design is part of why they feel so sleek and supportive under clothing. With the leg band, a little initial stretch with your hands can help “activate” the Liquifusion and ease things in right where you need a bit more room before wearing. Many folks with athletic builds find sizing up gives a bit more ease through the thigh while keeping that same adaptive stretch and support you liked. Really appreciate your recommendation and honest feedback — it helps others dial in the best fit for their style and activity. Thanks again!

    a nice line of underwear

    Unsure how I came across this brand, but my purchases have been easy and the fit is fantastic! Definitely will buy again!
