OMM Ultra Flexi Flask 500ml Straw
The Ultra Flexi Flask 500ml Straw carries more water than the 350ml version while keeping the same soft, collapsible design that compresses as you drink, so there's no sloshing or bouncing weight in your pack. A wide-mouth opening makes it easy to scoop from a stream or spring, or to add electrolyte powders without spilling, and the larger-aperture bite valve gives a strong, easy flow with minimal effort. The straw puts water within reach without needing to tip your head back mid-stride. Every part is interchangeable, so a worn valve or straw is a simple swap rather than replacing the whole flask, and at 55g empty it's an easy way to add capacity for longer days out.
