Small enough to fit in almost any bag, this bottle gives you that little bit more than the 500ml. ?Great for school bags, sports activities and day trips. Also a great size for sitting on your office desk to make sure you reach your daily hydration intake - refill 3 times a day and you hit your target! Fits in most car drink holders and sits happily inside a day back pack or even in a standard bike bottle holder. Easy to clean and the lids are top-rack dishwasher safe. Want something cooler?
