Light, Fast, Efficient
The QiFlow Sleeveless weighs just 50g. The lighter and thinner the vest, the more wind tunnels it features to reduce sweat absorption. This minimizes weight during races, making you feel lighter and enhancing running efficiency.

Full-Body Ventilation Mesh
Strategic ‘wind tunnel’ mesh holes, target the body’s high heat zones. During running, air passes through these mesh holes, creating direct airflow against the skin, carrying away excess heat, lowering the perceived temperature.

Minimal Seams, Maximum Comfort
Fewer seams and a seamless fit, reduce the risk of chafing, super-light barely-there feel . Maximum comfort and zero distractions for full race focus.
