The Streamliner: A classic 375ml plastic sports bottle, with a wider, easy-to-drink flippable plastic sports cap. It uses transparent shrinkwrapping to show off the fresh milk insde. It’s heavyweight boxer Ian Lewinson’s and fencing cadet Rajan Rai’s favourite bottle. “I wouldn’t normally associate drinking milk with training, but the design and shape reinforce the fact that milk could be a sports drink,” says Rai.
