Racing or training, take matters into your own hands. This minimalist soft-flask handheld features an innovative thumb loop that allows you to hold the flask securely without wasting energy gripping or squeezing. Versatile and ambidextrous, it can be held in either hand and the soft, neoprene loop provides a comfortable and chafe-free fit. The adjustable, sweatproof strap fits most hand sizes and snuggly stays in place with a Velcro-style closure. Topped with our SpeedFill(TM) Cap for quick refills on the go.
