Compressport ErgoFlask (500ml)

Instant drink without the hassle. The flask delivers water quickly without squeezing or slowing down. During tempo runs or races, you'll notice that you can easily keep drinking without losing your rhythm.

Compact and quiet while running. The flask shrinks as you drink, preventing it from sloshing or getting in the way. You notice this especially on technical sections where distractions can be disruptive.

Practical for long distances. It slides easily in and out of your vest or calls and can be refilled quickly at aid stations. Especially during ultras or hot days, this helps to keep moving efficiently.

If you are unsure about the volume, look at your distance. For short runs, 500 ml is often enough, but for really long stages, you need multiple flasks.
