    Works perfectly. These flasks are great. The bite valve works well and used with the Momentum Race Vest it makes it simple to drink on the move without slowing down at all. Love how they collapse down as you drink, so you don’t get the water sloshing around in the bottles.

    The best bottle! I’ve used every option out there and these bottles are the best so far! They are easy to fill, easy to add electrolyte to, perfect to drink from and fit well into back pockets of gear if needing extra bottles. Love these! Looking forward to using these at Bigfoot 200.

    This bottle is great! I use it with my momentum vest and so easy to drink from without removing the bottle. The bite valve is super easy to use too. I already want to get another one!

    This bite valve and bottle are great. The valve doesn’t leak like my other brand did- and the bottle mouth is big enough to add your own mix. I worked a three day aid station at the Moab 240 mile race and this bottle was the preferred choice. runners were stashing an extra in the back of their packs for use on the longer stretches.

    I can only give this 4 stars because the bottle itself is awesome and perform great, jsut with the straw portion was about 1-2 inches longer or have a way to put a longer one onto the cap (looks like the tube and cap are basically one) even with the magnetic clip (which come loose because no place to properly secure it on momentum vest) it flops around. Otherwise great item and still use it despite the minor annoyances

    Love this soft flask w/ a straw. Great for storing in your hydration pack in the front pockets. So easy to drink from, you really don’t even have to take it out of your pouch.

    Leaning far over to drink from a flask that sits low on my vest straps is rather unpleasant and I don’t like removing flasks to drink on the run. The long straw version of the softflask allows me to hydrate on the go without craning my neck. As a bonus I have not managed to puncture these flasks enough though I am notoriously tough on my gear in the mountains.

    Using with Nathan Pinnacle and Ultimate Direction Race Vests and both fit the bottle great. Material seems stronger than your typical soft flask.
