Logging miles on hot days or racing in the summer heat — staying cool is key. This minimalist handheld keeps hydration cool 38% longer than a standard flask. An innovative thumb loop allows you to hold the flask securely without gripping or squeezing. Versatile and ambidextrous, it can be fitted to either hand. The adjustable, sweatproof strap fits most hand sizes and snuggly stays in place with a Velcro-style closure. Topped with our SpeedFill™ Cap for quick refills on the go.
SPEEDFILL CAP
Designed for fast filling - flips open for quick refills and snaps closed for leak-proof seal.
INSULATED
Double-wall insulation technology slows heat transfer from the user, provides protection from outside temperatures, and minimizes bottle sweat.
HOLD WITH EITHER HAND
Versatile and ambidextrous, the flask can be carried in either the left or right hand, with or without the thumb loop.
THUMB LOOP
Innovative thumb loop allows you to hold the flask securely in either hand without gripping or squeezing. Soft, neoprene padding provides a comfortable and chafe-free fit.
ADJUSTABLE STRAP
Sweatproof strap can be adjusted to fit a wide variety of hand sizes, the Velcro style strip ensures strap stays in place while on the run.
EASY TO CLEAN
Hand strap is removable for cleaning. Flask and cap can be placed in dishwasher and the strap hand washed.
COMPRESSIBLE
Flexible design shrinks as you drink, reducing water movement and easily stores away in your pocket when empty.
