Camelbaks are never cheap but they are probably the best.
They are covered by a lifetime guarantee so they are built to last.
Would make a wonderful present for someone who wouldn't buy it for themselves because it is a high value item.
Please don't compare this with pound shop bottles which is made from bpa plastics and leaves strange odours in your drink
