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 — Minimalist but comfortable, the sweatproof strap can be adjusted to fit a wide variety of hand sizes, the Velcro style strip keeps the strap in place while on the run.

Easy to Clean — Handstrap is removable for cleaning. Flask and cap can be placed in dishwasher and the strap hand washed.
