These innovative 750ml Vac Cap bottles use a specially adapted, patented internal valve that 'switches off' the flow of liquid when pressure is released from squeezing the bottle, avoiding liquid loss. This also makes them far more hygienic than using the regular pull out cap nozzles if you have muddy, sweaty hands. And, you won't need to use your teeth to pull out the nozzle, so no teeth marks ! And, there are no chewable parts to present a possible choking hazard. Here's a bit more info -

• Has a large cap opening for an easy fill up (you can even add ice cubes) & is easier to clean out.
• With finger indents and pimpled grip finish for easy holding - a real pro bottle !
• Made from Hi-viz yellow, BPA-free plastic, making them much easier to see.
• Ideal for clubs, schools, cyclists (slots into bottle cradle) etc.
• Made in the UK

Go on, get stuck in !
