Collapsible Food-Grade TPU: Made from BPA-free food-grade TPU, the bottle compresses as you drink to help reduce water movement and folds flat when empty for convenient carrying
High-Flow Bite Valve with Dust Cap: The soft bite valve provides quick hydration during exercise, while the protective dust cap helps keep the mouthpiece cleaner outdoors
Temperature Range for Active Use: Designed for temperatures between 32F - 140F (0C60C), suitable for trail running, hiking and cycling, but not suitable for freezing or dishwashers
