How to avoid the layer of ice inside a water bottle during winter activities?
Yes it's bulky and has it's price. A major advantage is that you can attach it to your belt. So it's there isolated and ready to be drink. Fast and really more accessible than if you have to put it in your bag. Intensity of your activity can also determine if it's better to have it very accessible. But not everyone like that!
