Fit

Relaxed Regular Race

A women's-specific athletic fit — shaped to move with your body through every stride without pulling, shifting, or gaping. Comfortable from warmup to finish.

This is the best singlet I've run in. Half marathon in 86 degrees — stayed light the whole way, nothing shifted, nothing chafed.

— Emily R.

Breathes incredibly well, dries fast, fits perfectly. This is my race singlet now.

— Caitlin M.

Bought this for a summer training block and it's become my go-to for anything above 65 degrees. The ventilation is real — you can feel the difference compared to a standard running top. Lightweight, fast-drying, and the fit is shaped for how women actually run. No complaints.

— Jess T.

Outstanding hot weather singlet. The ventilation is the genuine differentiator. Stays light, moves well, fits right.

— Dana K.

frequently asked question

Is this singlet built for racing or training?

Both — and that's intentional. Light and clean enough for race day, durable and consistent enough for the training blocks that get you there. Most athletes end up reaching for it for both.
How does the fit work for women's proportions?

It's shaped specifically for women — longer coverage at the hem to prevent riding up, and a fit through the torso and shoulders that moves with women's body geometry rather than just being a smaller version of a men's cut. Nothing gaps, nothing pulls.
How does it hold up in the heat on longer runs?

That's exactly what it's built for. The ventilation is aggressive and continuous — stays light when you're sweating hard at mile ten. Fast wicking, fast drying, no heavy kit feeling.
Does it offer UV protection?

Yes. Built for long runs in direct sun without compromising on breathability or weight.
How do I care for it?

Machine wash cold, gentle cycle. No fabric softener — it breaks down moisture-wicking performance over time. Hang dry only.
