Stay hydrated and refreshed on the go, no matter where your adventure takes you

Dehydration can lead to decreased athletic performance, increased risk of injury, and decreased endurance. This is why it is important to drink enough water at all times. Threo hydration backpack was designed to you help with this no matter where you are.

Easy to use
Refilling and cleaning our water reservoir is a breeze, thanks to the convenient large zippered opening. This also allows you to easily fill the hydration pack with ice in case you want to keep your water cool.
The Threo water tank features a double seal. This ensures that it is airtight, even when it is subjected to pressure or intensive movement. You can put it safely in your bag without worrying about the tank leaking and damaging your belongings.
Made from food-grade PEVA material certified by FDA, this water bladder is BPA-free and does not contain any harmful chemicals.

Convenient carrying

The large handle and 2 locking holes allow the backpack to be securely fastened inside the bag, preventing it from bouncing or sliding during movement.

Efficient mouthpiece

The flexible hose, fitted with a high-flow valve, allows you to drink comfortably on the go. It also has a locking mechanism that prevents your precious water from running out. All this reduces the time and effort required to drink, allowing you to stay hydrated without interrupting your outdoor activities.

Capacity scale

With the volume marks, you can easily keep track of how much water you have consumed and how much you have left, ensuring that you stay adequately hydrated throughout your outdoor activities.

    Fits perfectly in a backpack with room for extra accessories! Very well made, and if don’t want to carry a large backpack, you still can carry around one liter of water to keep hydrated!

  2. Conor


    This is the perfect size for running. I bought it to put in my hydration vest for my long runs. It has never leaked, and it is easy to drink the water. Highly recommend 👍

  3. Malachy


    This is a really simple to use hydration bottle. All you need to do is fill it up, fold the top and slide the binder over it to lock everything in place. The opening for drinking is also very easy to use without hands.

    This water bladder allows me to take extra water with me when out in the nature with my family. We all have our water bottles but this product is very handy when it’s a time to refill. I can redistribute water from this bladder to my kid’s bottle with ease and without wasting any water. Highly recommend it

  5. Darragh


    This bladder holds a lot of water or whatever you put in it. I engage in distance running and bought this while training for my marathon. This bladder works just fine for that and doesn’t leak. Would recommend it.

  7. Zack


    We’ve been using these water baldders for hiking. They feel very well made and fit easily inside a backpack. It has also showed no leaking after multiple uses!

    Really pleased with this hydration reservoir. The sliding top section is so easy to use, I actually prefer this to the standard twist lids. Perfect for cycling, walking or running!
