We pioneered this category and continue to evolve it with light and nimble designs. Our flasks are designed to keep you performing at your peak. From nutrition needs to quick hydration.
Designed for the minimalist runner, the SkyFlask Speed features an adjustable hand strap and innovative, padded thumb loop to hold the flask securely in either hand without gripping or squeezing. Topped with our SpeedFill cap for quick refills on the go.
