Customer Reviews (4.8 / 5 · 5 reviews)

Joseph K. ★★★★★

The inseam hits that perfect middle ground—short enough to feel breezy, long enough that they don't ride up during my morning run. Wore one pair all day and forgot I had them on.

Stella ★★★★★

The fabric really is supersoft—I forgot I was wearing them by lunch. They hit that sweet spot between a short and a brief, so they don’t ride up or feel bulky. This pack’s already my go-to.

Amelia ★★★★★

The inseam is exactly the 4.5" I wanted—short enough to feel airy but not so brief that it rides up. The supersoft fabric has held its shape through half a dozen washes, which is more than I can say for my old pairs.
