Gregory3D Hydro 3L Day Hiking/Hydration Water Reservoir

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

This was a nice replacement for my 15 year old water solution that should have been replaced a while ago. The opening is great and it fits well in my existing daypack.

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!

Works great. Couple years in and no leaks. Handle makes fill easy. Definitely need to take a paper towel to finish drying around seams to get completely dry, but that’s any hydration pack.

First one ruptured. Ordered a replacement and it arrived already leaking. Third one came with a mouthpiece that doesn't dispense water.Quality issues aside, it's annoying that it doesn't have a cover for the mouthpiece either. I only use this because i have the compatible backpack.

Easy to fill, no leaks around the cap or bite valve. Seems to be built better than the Camelback it replaced.

I have had multiple brands over the years and this, easily, is my favorite one. Pretty straight forward. I’ll freeze some water overnight in it at the angle that doesn’t block the hose outlet, fill it up and use it! Easy to use, I like the magnetic adapter to keep the hose in place. When I clean it out, this is what I REALLY like. The sidewalls are just stiff enough not to collapse. This is a big deal for getting it to dry properly. Had a hook to hang it upside down.If you have looked at every single one on the market and can’t decide - go ahead and get this one.

I love the inserts in the bladder so it dries well. I also love the hook so you can hang it to dry. great product.
