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

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!!

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!
