The Platypus SoftBottle with screw cap is not like all other bottles. No, it is more flexible. The volume of the bottle decreases with every sip taken from it. Once the bottle is empty, you can stow it away very small. Once filled, the SoftBottle can also be placed anywhere. The screw cap also prevents leakage. Even the highest pressure simply doesn't bother this bottle. Hard to believe, isn't it? Try it out for yourself!
