Perfect Hydration Pack – Held Up Great in Chile!
Took this hydration reservoir on a hiking trip in Chile, and it was absolutely fantastic! The design is super user-friendly, with an easy-to-fill opening and a secure, no-leak bite valve. Even after hours of trekking in different terrains, it held up perfectly—no leaks, no weird plastic taste, just a reliable water source on the go. I also love how the 3D shape helps it dry faster after cleaning, which is a big plus compared to traditional hydration bladders. The durability is impressive, and it fit well in my pack without sloshing around too much. If you need a solid, well-designed reservoir for hiking or travel, this one is a winner. Highly recommend!

Excellent, works well, no leaks, no plastic taste that I can detect
The tube is long enough for me, the bite valve works really well, it's super easy to fill because of the "3D" design which also makes it easier to dry than any other pack I've ever had. No plastic taste that I can detect which was a huge problem for my on my last two packs. Build quality seems very good, no leaks from the pack, filler or hose. Three liters is a big upgrade from two for hikes in Summer Arizona heat. The built in hook on the bottom is very useful for hanging the pack to dry, and the no-leak quick release allows me to remove and fill the pack without having to thread the hose back into the pack and straps, and I can pre-fill the pack and store it in the refrigerator over night without the hose flopping around in the fridge. I also appreciated the minimalist recyclable cardboard packaging

Great water bladder
Worked great for hiking Rocky Mountain National Park. No leaks and very easy to clean. They have a magnetic attachment that's strong and won't come off even with streanious hiking. I put ice packs on my blader compartment and keeps the water cool in those hot summer months

Sturdy for long climbs
Love this hydropack! It is very sturdy and easy to clean. 3L works perfectly for long climbs or hikes. Only wish it came with a mouth piece cover already attached.

Best water pouch
Great hiking bladder. I was looking for an affordable quick option for water while hiking, and I am very happy I bought this one. It is very easy to use, has no leaks, and is very durable. The design is option as it fits in many backpacks and the little magnet attachment for the tube is amazing for keeping it in place.

Too small
Quality is fine but way too small, particularly because i ordered the 3L and they sent me the 2L twice and weren’t able to make it right. Amazon doesn’t want me to mention that in my review but it seems pertinent.

Even if you don't have a Gregory bag, take a look at this hydration system.
Oh my goodness, this hydration bladder is all the things. I just picked up a Gregory Zulu 24 LT, with the little hook to hold it, so I swapped out my old hydration bladder just for the hook, with no idea of the other features I was going to love. The "hanging clip" on the bottom is brilliant, allowing you to dry out the bladder without any trouble. I just leave it hanging now, ready for my next adventure. The material is excellent, and it holds its shape both while you fill it and empty it. The quick connect and release works perfectly, and I love the handle on it for keeping it steady while filling. I have come to realize that I am a lazy hiker, who wants to get out there, but is also looking for an excuse not to, and this is one of those pieces of equipment that is so streamlined and sensible, you will use it twice as much, and be pleased with your purchase every time you do. Excellent.

ich habe die gleiche Trinkblase schon einmal ein älteres Modell. Die Trinkblase ist bei jeder Wanderung, die ich unternehme ein Muss. Durch die jahrelange Benutzung ist die Blase etwas unansehnlich geworden, will sagen, sie ist einfach abgenutzt, jedoch voll funktionsfähig. Bin von der Blase begeistert und habe sie mir noch mal in einer moderneren Version gekauft. Die Trinkblase kann ich wirklich empfehlen, durch den Griff ist sie leicht zu befüllen, natürlich ist sie dadurch etwas schwerer als Blasen ohne Griff, aber he, das weiß man vor dem Kauf. Sie ist auslaufsicher, leicht und "wackelfrei" im Fach des Rucksacks zu verstauen, nimmt wenig Platz weg trotz ihres Volumens und ist sehr stabil. Der Schlauch und das Beißventil sind sehr gut hochwertig, und die Magnethalterung für den Schlauch ist prima, dadurch baumelt nichts am Rucksack rum und man hat den Trinkschlauch immer parat. Die Trinkblase kann ich jedem nur empfehlen!!
