HydraPak UltraFlask Speed 600 Water Bottle
Weighing in at just over an ounce, the HydraPak UltraFlask Speed 600 water bottle is so light you might forget you brought it—that is, until you need a quick drink during a long-distance run.
- Soft material confroms to most hydration vests, belts or pack pockets (not included)
- Flexible design shrinks as you drink, helping to reduce water movement while you're running
- Choose between 2 cap configurations depending on your run or vest—directly mount the bite valve onto the cap or insert the adjustable drink tube to create a straw cap
- Included straw can be cut to any length
- High-flow bite valve auto-seals after each sip, eliminating annoying drips
- Speedfill™ cap flips open for quick refills at aid stations and snaps closed for a spillproof seal
- Large standard 42 mm opening lets you fill the flask easily with ice and drink mixes

They fit into the Salomon ADV vest pockets fine.
I run Ultra distance primarily with a Salomon ADV skin 12 vest. I've wished that the standard 500ml flasks that come with the vest were larger. I was unsure if these 600ml flasks would fit in the vest. The measurements given for both the Salomon and these 600ml versions appeared to show that they would not fit (too tall), but apparently the two companies don't measure from the same points because these 600ml hydrapak flask are actually every so slightly shorter than the 500ml Salomon versions. In summary, they fit fine in the Salomon vest. They are tight and are just a bit harder to get in the vest, but I've learned how to slip these larger versions in quickly with just a little practice. Very happy.
Great bottle, tired of these mouth pieces
I got two of these to replace the smaller HydraPak soft flasks that came with my Salomon hydration vest. They're awesome and hold more! Wins all around. I've used this specific bottle for two ultra-marathon seasons and almost daily training. I don't baby the bottles, although I'm also not a monster and don't abuse them either, and they've held up wonderfully! The soft flask itself has been impressive, as has the lid with the wide-mouth opening! Great for refilling and cleaning. Zero issues. I will get more if anything eventually goes wrong with mine. Highly recommend! However, I have a general qualm with these mouthpieces that so many bladders and soft flasks use these days. Granted I use mine a lot but it's amazing how fast these soft mouthpieces split from normal use (and the presence of teeth, I suppose, but I actively try not to bite hard). Once they split, they drip and leak. The mouthpiece is my only negative thought about this bottle, a minor one. Definitely recommend it for runners and hikers!
Better than the flasks that came with Salomon Vest
Love these flasks. Replaced the flasks that originally came with my Solomon vest. The UltraFlasks are SO much better. I love that the tops have a ridge which, when I stretch the strap around them, prevents them from migrating lower into the vest pockets...they stay in place (the originals were always slipping down). Also love the 2 top options. I have used both the original and the hose attachments (settled on the hose attachment as it makes it easier for me to drink) and really appreciate both options, especially since I had to replace the original flasks because the tops got destroyed. Great product!
Works perfectly for hard ultra running
The short cap with bite valve works great. The cap with the tube and bite valve leaks. The bag - bottle is tough and no detectable plastic taste. It’s a welcome replacement to hard bottles especially for running on technical terrain. The 42 45? Mm opening is compatible with the filters that are out there.
Tough to handle
To be fair, this HydraPak collapsible water bottle does everything it is supposed to do. In my situation where it comes in and out of my backpack at airports, gets filled, emptied, and filled again, and is carried in tight spaces, it was very difficult to get used to. I also popped the entire top off unknowingly and dumped the whole thing in a rental car because, of course, it doesn't "stand up" like a conventional bottle. It also doesn't have a straw capacity and it difficult to tip up to drink with one hand. I want to like it, but I really don't.
There is a problem..
It's significant feature causes a problem. You can flip open the top and reveal a guzzle spout; but nearly impossible to snap it back into position with the lid on as the latch is very close to the top of the lid.
Great fit, easy to hydrate
Great product - fits perfectly in the front chest pouches of my Nathan trial vest.
Bad chemical taste
The bottles work very nicely, and the flip cap and extension hoses work nicely as well. However, the bottles impart a terrible chemical taste to the water content; I hoped this was temporary and tried to rinse, clean, and"soak" the bottles in water to get rid of the taste, but it doesn't work. I've left the bottles filled with water for 6-8 hours at a time for probably 20 times so far. The taste has lessened a bit from the first sip that left my tongue feeling "odd", but the bottles still impart the chemical taste to the water within minutes of filling them.
Hi , We apologize for this inconvenience. As a leading provider of performance hydration, any issue with our product is taken seriously. Our products are made from a food-grade thermo-plastic urethane (TPU). We have used this material since 2001 and it is used by many of our competitors. It is the industry standard because of its food-safe properties and its durability. TPU is BPA free and non-toxic. Unfortunately, a small percentage of flasks have an unpleasant taste, which varies from person to person. Please try to following to reduce the taste issue: 1) Fill the container up with water and add a few drops of lemon juice. Then place into your freezer and let it freeze overnight. Then thaw it out and rinse. The taste should be diminished. 2 ) If that does not work, you can fill the container up with milk and place into the refrigerator for 24 hours. Then clean and dry the bottle. This should also help. If neither of these solutions work for you, please let us know and we will be happy to send you a replacement. Please fill out a warranty claim I will link below. https://support.hydrapak.com/hc/en-us/requests/new?ticket_form_id=913128 Thank you!
Great product but awful initial taste
The plastic taste is initially pretty terrible, hence the 4 stars. I spent a couple of days soaking them with baking soda water and rinsing them out with a dilute vinegar solution, which helped tremendously. I would love it if Hydrapak could fix the taste before shipping these products! Once the taste was tolerable, I liked these bottles a lot. They fit perfectly in the taller chest pockets of my BD distance 8 vest. The tube is a good length for me to use, but would fit the BD pack a little better if it were like a half inch longer. The flip cap feature works better than I expected and holds watertight, but I won’t be surprised if they start to fail in a few years. Overall recommend, but make sure to give yourself a few days to clean them out before you use them!
These 600ml versions do fit in the Salomon vests
I have been using the standard Salomon 500ml versions in my ADV vest but wanted some extra capacity on certain longer, dry runs. These fit in the vest perfectly and I was able to custom cut the extensions to the perfect length. The flip top takes just a bit of getting used to to both make sure it securely closes (push until you get a VERY pronounces "snap") and getting that snap without spraying fluid everywhere (hang on only to the rim of the flask, not the flask itself). Couldn't be happier. LOVE THEM!!
