About Soft Flasks

The compact 200 ml Soft Flask is designed for runners and trail runners. It fits securely inside the nerd belt NBracer and Phone Belt, making it ideal when you only need a small amount of fluid. Its wide 32 mm opening makes refilling easy and allows you to add small ice cubes, while the fast-flow valve provides quick access to your drink on the move.

The larger 500 ml Soft Flask is designed to fit comfortably inside most running vests. Its 45 mm opening makes it easy to fill with water or drink mix, providing greater hydration capacity for longer runs, races and days on the trails.

Both flasks are BPA-free, recyclable, dishwasher-safe and freezer-safe. Their soft, compact design becomes smaller as you drink, helping to reduce bulk while keeping your hydration close at hand.

How does it work

The flexible flask holds its shape when full and gradually becomes smaller as you drink. This reduces empty space inside the flask, helping to limit movement and making it easier to carry inside a running belt or hydration vest.

Choose the 200 ml flask for compact hydration in the NBracer or Phone Belt, or the 500 ml flask when you need more fluid in a running vest. Both sizes can be used with water or sports drink mixes and cleaned by hand or in the dishwasher after use.
