500ml Collapsible TPU Soft Flask with Cap Water Bottle for Trail Running, Marathon, Triathlon, Hiking

Our soft flasks are designed to conform to the shape of your body, compressing as you drink. This means reduced sloshing and bouncing, less spillage and easier drinking.  This flexible 500ml flask compresses as you drink it to eliminate water bouncing inside and reduce sucking effort. The blaster valve helps keeping the flask leak-free until you bite it.

Product Description

Why do we use soft flasks?
There are dozens of good reasons to stop using disposable plastic water bottles: cost, environmental impacts, health dangers like
the leaching of chemicals into your drink, etc.

It was only until recently that a product that is such convenient for long distance or trail runners has become available. Enter
in your search Collapsible Soft Flask, a compact and reusable way to stay hydrated while running or traveling. These water bottles
take up minimal space in your pack or pocket when empty, and their flexible designs shape to your hand and body, so they will
never be unwieldy when being carried.

Stow a couple in a hydration vest, carry one in your hand, or just hook a line of them to your utility belt until it looks like
you’re a well-hydrated Batman—you’ll never have to buy a single-use plastic bottle again.
