- Gregory 3L 3D Reservoir

My last 3 liter hydro pack got a pinpoint hole in it. Not sure how that happened. I’m pretty careful with it. I like this narrow version. It fits in my Salomon running pack better. This is a great pack because it’s easy to fill. Nice hanger hook so you can dry it upside down. The magnets are great for attaching to the chest strap on my backpack.

I really like the design features and fitment to my Gregory baltoro backpack. It cleaned up easily and despite my worries about it in a very very full backpack it held up very well with no leaks over a 7-Day rugged trek covering 50 miles. After having had bad experiences with other bladders, I have to say this one's changed my mind. The material is tough and I really appreciated having the water easily available to hydrate on the move. Even if you don't have a Gregory backpack I would still recommend considering one of their bladders just make sure it's going to fit your pack. I have a small 35 l pack that this 3 l bladder might be too big for.

The Gregory 3D is absolutely fantastic. I've never owned one that was this easy to dry and clean (I hung it up for a day and only had to hand dry a small portion near the lid). The resivour itself was also crazy easy to fill, and the material seems sturdy. It was easy to drink from and lock on the trail as well. If you're an ultralite hiker, this product probably isn't for you. It's not heavy by any means, but lightweight isn't it's goal either. It's built to be sturdy and easy to fill and clean. That requires it to be a little bulky and little more rigid. It takes up 3L of room (as you'd expect), but it's more narrow horizontally and more thick vertically, so you might need to adjust your item placement. Would absolutely recommend this to anyone.

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

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

The construction on this bladder is very weak. In the two years I’ve owned it, I’ve used it maybe 5 times, none of the hikes have been strenuous. I pulled it out after a few months to go hiking again and when I filled it, it was leaking through the plastic. I have a Gregory pack and love it, so I was pretty disappointed that this couldn’t hold up.

Great bladder for my Gregory backpack. Easy to fill and doesn't leak. Holds 3L. Very easy to drink (suck) from the hose. It served me well for hiking in the grand canyon and other long hikes where I needed to carry a lot of water.

Survived EDC ‘26! No leaks, easy to fill and clean. I like the magnetic addon for the tube.

Great sturdy pack and dries well. Just what I was looking for. Fits my lowe alpine active airzone pro

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!!
