With a thermomoulded bottom, wide 42mm cap and high-flow valve, the SOFT FLASK 500ml/17oz SPEED 42 makes drinking, refilling and storage even faster and easier, so you can stay focused on the trail ahead. Shrinking as you drink to limit water bounce, the flask lets you know exactly how much water you have left. The large 42mm opening makes it easy to fill with ice or energy mixes.
The 42mm opening is compatible with the Soft Flask Straw and the XA Filter Cap 42.
