The secure valve allows you to drink without needing to open or close your flask. Its profile offers additional comfort and makes it easier to slide or store the bottle. As you drink, air is released, and the bottle compresses to prevent slipping. The functional bottle is compatible with most hydration packs and is made from recycled TPU!
