In order to purchase (for obvious reasons) a quality product, I chose the reliability of the Salomon brand. Unfortunately, I was not fully satisfied as the water takes on an unpleasant taste from the plastic material of the container. The unpleasant taste remained even after daily washing or filling the container with vinegar. However, I can say that after using baking soda + lemon juice, filling the container with water, and letting it sit overnight, the strong taste that the plastic left in the water was dramatically reduced to the point where I can now use it. The DIFFERENCE was noticeable from the very first time I applied this tip. I have been using it for a month now. It doesn't leak, the seams appear to be durable, and the liquid comes out of the flask by lightly biting the rubber of the spout. It does not have a hook. You either hold it or place it in a special pouch on your belt or vest.

It is convenient because it offers minimal insulation without the weight of metals, but it certainly does not provide the insulation durability of metals.

One star, it has a terrible smell of plastic and silicone even after numerous washes. I thought it would go away at some point but in vain. What a waste of money... I will give half a star just for the concept.

There is no need to say much, it simply does what it should and how it should. I have 2 identical ones, in one I only put water and in the other I have water with electrolyte. It doesn't leak at all, if you wash it after each use and store it dry, it doesn't have any problem with plastic odors, etc. I recommend it, I consider it one of the best on the market.
