Gregory3D Hydro 3L Day Hiking/Hydration Water Reservoir

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!

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.

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.

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

My wife runs long distances and needs a durable hydration bladder. This one was highly rated but had started leaking from a seam after only a few uses.

Finally found a decent hydration bladder that doesn’t leak, and I love how it disconnects near the top instead of at the base. Very happy with this purchase.

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.

No leaks and definitely easier to clean than my last reservoir. I don't have a particular need for the detachable tube, but it's nice to have the option of swapping out bags if I wanted. 3 cheers for the magnet clip that comes with the reservoir which makes managing the tube much easier.
