We teamed up with visual storyteller and designer Greg Itahara to bring our fastest singlet yet—the AeroFly—to life.
Greg’s two-sided design captures the full journey of every runner:
One side represents the grit, grind, and dedication it takes to show up at the starting line.
The other side celebrates the triumph of race day—the push, the finish, and the pride of achieving your goal.
The AeroFly isn’t just built for speed—it’s built to tell your story.
Designed for the hottest months of the year, this singlet is so light you’ll forget you’re even wearing it. And with bonded seams that banish chafe, you can focus on your stride—not your skin.

I have two of these singlets now and they fit so nice! So light and breathable for hot summer runs. I like the thin material and the simple solid colors. They go with pretty much any pair of shorts.
This is the singlet!! When I first saw it I was thinking it might be see-through as it was so thin but it wasn’t and the perfect blend, feel, and fit. Fits true to size and looks super rad on! I need more.
