Feeling good for moving
Hold great while walking/biking. The fit/support for daily use / deskworking is not as good as the trunk version. Still pretty happy with it.

Hi Louis. Thanks for the feedback and for giving the Aspire Long Boxer Brief a try—really glad to hear they're holding up great during your walks and bike rides. You're picking up on exactly what the longer inseam is designed for, which is that locked-in performance during movement and activity. The difference you're noticing during desk work makes total sense. The Long Boxer Brief's extended length is optimized for that active support, but when you're sitting for longer periods, that extra material can sometimes feel less ideal compared to the trunk's shorter, more streamlined cut that's better suited for all-day comfort in various positions. It sounds like you've got a good read on how each style performs in different situations. The trunk length tends to hit that sweet spot for daily wear and desk work, while the longer boxer brief really shines when you're on the move. Appreciate you taking the time to share how they're working across different activities—it's super helpful for others deciding between the two lengths.

Prefer the Aspire for over the others. They don’t ride up at all. Size up though.

Very comfortable
This underwear fit perfectly. It is so light. It feels like wearing nothing. My only concern is the summer heat in Phoenix. I don't know if things will heat up down there.

Another winner!
These are easily my favorite boxer briefs from AsWeMove. The length is spot-on—it hits that perfect balance where you get great coverage without feeling like you’re wearing compression shorts. It stays in place all day with no riding up, which is a huge win.
The fabric is where these really stand out. It’s incredibly soft, lightweight, and breathable, but still has enough structure to feel supportive. You almost forget you’re wearing them after a while.
Overall, they nailed the fit, comfort, and length on this model. Definitely the best option in their lineup.
