    Great fit!

    These are easily some of the most comfortable boxer briefs I’ve worn. The fabric is soft, breathable, and stays smooth all day with zero adjusting. The quality is impressive too — durable stitching and great stretch. Highly recommend.

    Interesting Product

    Very smooth and light product. There is actually one seam across the crotch but, it doesn't seem to be an issue. Sizing is a little off for me I need to try a larger size. Give these a try!

    Thanks so much for taking the time to share your thoughts! We’re glad you’re enjoying how smooth and lightweight the Aspire Boxer Brief feels — that adaptive Stealthskyn™ fabric and Liquifusion™ design are all about delivering comfort that feels like a second skin. We hear you on the fit — since this cut is engineered to mold to your body heat and contours, sizing can feel a bit snug at first, especially around the crotch area where the contouring is more defined. Trying an XL or even sizing up again can make a noticeable difference in both comfort and how the brief moves with you. Also, if you’re looking for a slightly different fit or coverage, some of our customers find the Aspire Long Boxer Brief or the Aspire Aero Brief offer a feel that might suit varied activity levels or preferences even better. Really appreciate the recommendation — thanks for helping others make informed choices!

    thumbs up

    Love the material and love the color but it’s tough being between two sizes. They either want to squeeze me and leave lines under clothes when going with the smaller size or they want to slide down in the back when they’re the bigger size. I still love them though!

    Thank you so much for taking the time to share your thoughts — and awesome to hear you’re loving the material and color! A lot of people really enjoy how the Aspire Boxer Brief’s adaptive Stealthskyn™ fabric molds to your shape with movement while giving that smooth, comfortable feel throughout the day. Being between sizes can be tricky — especially with a heat-activated, contour-forming design like this. While Aspire is designed to stretch and adapt, sometimes going with the Long Boxer Brief version can help give a bit more coverage and keep things from shifting at the back without feeling too tight up top. Also, the Liquifusion technology in the waistband and leg openings is meant to react to your body heat for a tailored, threadless finish that stays put. Some people find that paying close attention to the size chart helps dial in that “just right” balance between support and movement — and if you’re ever unsure between two sizes, we’re always happy to dig into fit details with you. We’re really glad you still love them overall — thank you again for the thoughtful feedback!

    Aspire boxer brief

    They feel great! Just be mindful to give the elastic around the leg opening a quick stretch. The aspire line seems to be a little more constricting than the dominate line. But still extremely comfortable! I keep ordering these a few air at a time so my wife doesn’t lose her mind!

    Adam, thanks for the 5-star review and the pro tip on the leg opening stretch — that's solid advice for anyone getting familiar with the Aspire line. You're absolutely right that Aspire has a more structured, locked-in feel compared to Dominate. It's engineered with that responsive compression and support for when you want that dialed-in containment. The fact that you're still finding them extremely comfortable means they're doing exactly what they're designed to do. And we love the strategic ordering approach — a few pairs at a time is definitely the way to keep everyone happy while building out the rotation.

    Michael, thanks for the 5-star review and love for the new color! That's exactly what we built Aspire for — that versatility to handle everything from intense training sessions to laid-back weekend vibes without missing a beat. The responsive compression and structured support are designed to move with you whether you're pushing through a workout or just lounging around. It's awesome that you've found that perfect balance where one pair can truly do it all. Appreciate you being a longtime fan of the line.

    Best Performance Yet

    This underwear is so good i try to do the BOGO when a new color is released. The Aspire Boxer Brief has improved over time to be my go style. I started with the trunk early on but wanted something more form fitting so i went with the boxer brief. Keeps me cool and forms to my body like a glove. Wicks away any sweat. I tried many many, others and the Aspire Boxer Brief outperformed them all. I received a defective pink pair and customer service asked for a pic and then send me another pair. Excellent service.

    Super soft and thin

    The fabric is extremely thin and super soft. They take up no room in a drawer or bag. I would recommend and will buy more.
