Osprey Hydraulics 500ml Soft Flask Water Bottle

a lot easier to store and fit in various pouches than a hard bottle and its quite durable. even if it does break, Osprey has a seamless lifetime warranty process on all their products so youll get a replacement super fast. the bottle cap is easy to take off all the small bits which is good because you should be cleaning the inside of the mouth piece often to avoid bacteria build up ( which you could see clearly through the opaque parts). does not spill and only dispenses water when the tip is compressed so its great!

Great for running or hikes, works great, no plastic taste. Easy to clean and doesn't leak.

Bottle worked great. Easy to fill with the wide lid and it doesn't leak. I was even able to drink from my chest pockets without having to take it out.

I've bought two and took on multiple multi-day backpacking trips. They collapse down for easy packing when empty. They've held everything from water, orange juice, gatorade and tequila and have never had any leaks. They did not stain or hold old flavors. The only drawback is trying to shove a "limp" (half full) bottle back into a side pouch on my backpack. It's a laughable situation.

I purchased two of these soft flasks to go in my Osprey Duro running vest. I like these flasks because I can easily access them while running. I alo like these flasks because they are easy to take out and refill at a water station without having to take off my vest. These flasks are also easy to clean versus the bigger bladders. I got these for a great deal. They never leak either.

Exactly what you ask for. Easy flask running water bottles to use on the go. Not sturdy at all so best paired with the osprey running pack. Highly recommend!

Plastic aftertaste and smell. Meh.... Why can't they be made of silicone?

Functional and easy to clean. No noticeable plastic taste when drinking. I like this size for mixing with a single serving electrolyte solution. The compressible soft body means you'll suck up every last drop on your runs.
