VEST PACK FIT

• Soft material conforms to most hydration vests, belts or pack pockets, makes a great addition or replacement running flask.

COMPRESSIBLE

• Flexible design shrinks as you drink, reducing water movement.

SPEEDFILL CAP

• Designed for fast filling - flips open for quick refills and snaps closed for a leak-proof seal.

CUSTOMIZABLE CAP

• Choose between two cap options. Directly mount your bite valve onto the cap or insert the adjustable drink tube to create a straw cap (can be cut to any length).

HIGH-FLOW

• Easy to drink bite valve auto-seals after each sip, eliminating annoying drips.

WIDE OR NARROW FLASK

• 500ml flask features an arrow flange for skinny and longer vest pockets. For wider pockets, the 600ml flask features a wide flange for a better fit.

LARGE OPENING
