Go big. The largest of our ultra-light series, the UltraFlask 600 holds more so you can go the distance. Its soft material allows it to fit snugly in most vest pockets and it shrinks as you drink to minimize water movement.

How do I clean my ultraflask?
All of our SoftFlasks are top-shelf dishwasher safe so they are very simple to keep clean. If you are fueling with energy gels or mixing your own nutrition mix, we recommend using a bottle brush or Bottle Bright to clean out any residue. The bite valves and tubes can easily be removed for cleaning as well. Our Cleaning Kit provides you with both a tube brush and tablet of bottle bright to soak your valves in.
