Less suited to: carrying a full day of plain water. For that, look at Hydration.

Plenty of runners have a fuelling recipe that works for them, and this bottle carries it neatly. The silicone is easy to clean and does not hold onto flavours. A good partner to the larger soft flasks when you want fuel and water kept apart.
