Review on Hydrapak UltraFlask Collapsible Soft Water Bottle For Hydration Pack by Brandon Reynolds

I got two of these based on a suggestion from a friend. Was excited to use them on upcoming 50k race and 40 mile runs. However, the straw (extended) top on one unit is extremely difficult to get on the bottle and doesn’t hold water without leaking badly (all over my chest while in my vest) and both tops are hard to get back on. Nothing like struggling to get the cap on a filled water bottle at an aid station during a race when you’re cold and tired and trying to keep moving. Very disappointing.
