I have exactly the same one from the same company, and in two separate containers.
That is, a 3-liter bladder split into two 1.5-liter ones. I have also reviewed that one.
So let's move on to this one now.
Let me tell you my reasoning.
I had bought the 1.5 + 1.5 liter bladder and had put 1.5 liters of water with electrolytes in one and 1.5 liters of water in the other, but the electrolytes I need (I do enduro) are ultimately much more than that. I consume 1 liter of fluids per hour, so I said I would get the same one in a 3-liter version without the divider and put in the corresponding amount of electrolytes as well.
The bladder is very good. I have fallen off the bike many times and crashed to the ground on my back and it has not leaked a drop.
I have other bladders too, but they are not like this one.
It is exactly as it should be, but the quality is very good.
At first, with the first one, I was hesitant because of the price, but I was very satisfied, so I also got the single 3-liter one from the same brand.
Buy it with your eyes closed. You won't regret your money. It has been tested in difficult conditions and has turned out very good.
If it came in a 4-liter version too, I would buy it.
An update, then: at the base of the hose that is on the bladder, mold has collected that cannot be cleaned. It is inside. Even though I clean it and wash it (and the water hose with a long brush), it cannot be cleaned there.
I am very satisfied because it has no leaks and is very durable, but this is a big minus. A very big one. It should be removable there too so it can be cleaned.
For that reason I deducted 3 stars. It is a health issue.
