Easy-to-fill, red 500ml soft flask with two drink valve options for quick and efficient hydration on the run.

The days of rigid water bottles are long gone in trail running. Our convenient, flexible ErgoFlask combines practicality with efficiency and ergonomics to make hydration easy. The smooth outer surface and an updated, slimmer shape allow the trail running flask to be slid easily into a bag, trail belt or pack. The wide opening helps to fill quickly at aid stations during a race, saving precious seconds. Guaranteed leak-proof, the flask shrinks as the liquid disappears, preventing sloshing and taking up minimum volume when empty. The fast-flow bite valve is intuitive, perfect when your attention is focussed on the trail underfoot. A second cap with a long drinking tube is provided as an option for those who prefer to drink without removing the flask from their pack. Eco-friendly and durable, the flask is guaranteed 100% PVC and BPA-free so you can safely use it, wash it and use it again. Simply put it in the dishwasher for easy cleaning when you get back home.
