Absolutely love them. They are breathable light and do not get sweat logged
This has quickly become my go to hotday racing singlet. I live in a very hot and humid environment, so this singlet has kept me downright cool during some of the more uncomfortable running weather.
Used the singlet for Woodlands 2026 marathon, has an amazing quality, no chafes, fast dry. Perfect fit
