This product is suitable for all who stroll in the park, go in for sports, walk in hot weather. Does not take up much space in the bag. A very necessary thing to quench your thirst. A bottle of water is suitable for my wife, she is engaged in fitness and she needs to take water for training in the gym. I give my wife this new thing that she needs. She is happy with a useful thing. Very light, odorless. The view is beautiful.
