So many flasks, so much water!
Recommended in Cocodona 250
I usually put my filter top on this 500 ml soft flask. With good planning and a filter, I am usually fine with 1 L total water capacity on most of my trips (two 500ml soft flasks). One thing to be mindful of if you are not using the filter cap and are storing this in your pack is that the Speedfill cap can come undone!

Easy to fill and designed to fit a wide variety of pockets, we use these flasks for water and electrolyte drinks alike on long runs. Generally carry two, both up front, but sometimes one is enough if it's not too hot as there is quite a bit of available water on the Leadville 100 course.

I use these bottles for every run, race, and adventure! They limit the "slosh" feeling and don't bounce around. The snap bottle really helps with easy re-fueling.
