Multi-Capacity: Our soft water flask is available in 3 capacities, 150ml/5 oz, 250ml/ 8.45 oz and 500ml/ 16.9 oz, so you can choose freely according to your needs.
Ultra-Compact and Squeezable Design: Made of food-grade TPU (thermoplastic polyurethane) flexible and lightweight material, BPA & PVC-free, the soft water bottle can be easily collapsed when empty. Its squeezable nature allows you to easily control the flow of water during activities such as running or hiking.
Shrink as You Drink: The flexible material allows the bottle to shrink as you drink, reducing its size and minimizing sloshing. This feature is particularly useful during runs or hikes, as it ensures the flask remains compact and comfortable to carry.
Collapsible and Space-Saving DesignWhen empty, the soft flask can be folded, rolled, or flattened into your pocket or bag making it ideal for running, hiking, cycling or gym use. This feature minimizes storage space and adds convenience for on-the-go lifestyles.
Tips for Use: To hydrate, simply softly bite the mouthpiece and press the soft water flask to enjoy! The harder you press, the faster the liquid will flow out. We recommend rinsing the flask thoroughly before first use. If the water flask smells you can try the following tips: Fill with milk, shake and rinse or add a drop of lemon juice, or let the tea bag sit in the bottle for a few hours. Recommended temperature range -20°C-60°C.
