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.

The name speaks for itself but this singlet really is the lightest and most functional kit that I own. You might pick it up for the first time and think you can see right through it but then you'll put it on and feel the high quality fabric texture that doesn't chafe your chest in addition to the smooth seams vs. the typical stitched kit. A true game changer for speed work or trying to survive a 14 miler after eating 5 tacos.
Light, durable, great fit, sweet design
This singlet is so light weight it feels like it's not even there.
Bought this one for my half marathon race and it performed beautifully. It’s very light and breathable, feels almost like you’re not wearing anything.
Light weight, comfortable, breathable. Not too hard on the wallet for the quality. If they keep putting out products like this. They have my money. Excited for more to come.
