OMM Ultra Flexi Flask 500ml Bite Valve
The Ultra Flexi Flask 500ml Bite Valve is a soft, collapsible 500ml flask built to compress in volume as you drink, eliminating the sloshing and bouncing weight of a rigid bottle. Durable TPU construction gives it a secure, textured grip, and a wide opening makes refilling or cleaning at a tap or stream straightforward. The interchangeable bite valve allows a quick, one-handed drink without unscrewing a cap, while keeping the flask spill-proof in storage. At just 29g empty, it's one of the lightest ways to carry extra water or diluted electrolytes on a run, hike or multi-day trip, and every part can be swapped out individually if it wears out.
