Just to right size
Just the right size and features. The 3L size is large enough for personal use on a trek. The size is sufficient for use around camp hanging from a tree for cooking and casual consumption useing the lid spout. The handle is convenient for filling and caring

I'm a fan
I have personally never been a fan of water bladders. I never met anyone who had one that didn't leak, take up a lot of space in their pack when full, or generally just have trouble with them. I really liked how this water bladder acted like reservoir for filling up larger pots for boiling water, I like how the connection from the water bladder to the hose is secure and easy. I also thought that the mouthpiece on the hose was nice. Instead of hanging the water in the pack towards your back I opted to put the water on top of my gear just under the brain of my pack. I definitely lined my pack with a garbage bag before I did this in case there was a leak. But there was none. I liked having the water bladder there for refill and access to the hose. I took a short day hike with my pack and instead hung the water bladder closest to the back of the pack and it worked really well there as well. I really enjoyed this water bladder I thought that it was really great for not only base camp but also for having in your pack. I especially liked how there was a magnet which could hook onto your chest strap in order to hang your mouthpiece so that it didn't get dirty.

Perfect Water Bladder
I've been using this for a few years hiking and backpacking. It's a great size and I love how it converts from a hiking bladder to a backpacking bladder and evenly distributed the weight on the top of the pack. The option to use it as a camp water is nice, it had a spiket under the cap. I'd buy this again and actually have two of them.

Works great
Used this on my first backpacking trip, worked out wonderfully. I hung it from a tree and it was so much easier than constantly pouring from a bottle or from the tube. Worth every penny. Also didn’t leak or anything when in my pack.

Durable hydration pack but took forever to dry
I used this hydration pack on my Kilimanjaro trek, and it held up well being jostled around in my day pack and never leaked. I liked how there were different ways to use it (backpack mode, camp mode, etc) but didn’t really use it for anything other than in my backpack because an actual water bottle felt more practical at camp. I previously had a 2L Osprey hydration pack but wanted to upgrade to a 3L pack instead. My biggest complaint about this product compared to the Osprey is that it was extremely difficult to get it to dry after using it. I’m sure it would be easier with a tool to reach inside or a hair dryer, but I hadn’t bought the cleaning accessory pack and was traveling for a few more weeks after using it. I tried shaking it over and over again, but it took about 4 days to fully dry on its own with the screw top open. Overall, I prefer the Osprey hydration pack because it has a wider opening and allows you to reach a hand in to clean and dry it without having to purchase an additional accessory kit like you would have to for the Gregory pack.

Really nice shape and convenient to use and hang
I really like the shape and ease that it dries when done with the trip

Dangerous Flaw
Reservoir seems fine unless cleaning through that small hole becomes an issue with my patience. But the bite valve just broke in two while I was far from a water source and water began spewing out before I noticed it. Other reviews with the same bite valve on the other 3L bag had the same issue. I’m not fond of negative reviews but this flaw could really get someone in trouble. I was able to keep it above my shoulder and ration water for a half a day and it was fine if a little dry. But this needs to be fixed. I like the camp function of being able to fill things up easily from the spigot under the cap but I can’t be solo in the backcountry with the possibility of losing a half a day of water unexpectedly. I just submitted my second customer service request and upon thinking more and seeing reviews with the same issue for the other 3L reservoir I decided that this should be a known and a fixed issue. Greggory, fix the issue and the reservoir would be great. Otherwise it’s dangerous.
