When it needs a clean, just pop it in the dishwasher. £9.99, firebox.com {3} Aquatina A graduate of Dragon's Den, Aquatina is a collapsible water bottle that fits flat in your pocket when empty, and then expands, concertina-like, to hold 500ml when full. Fully dishwasher-proof, too. £9.99 for two, aquatina.com {4} Hydracoach Intelligent Concerned you're not getting the hydration you need throughout the day? This bottle monitors the total amount you've drunk from it that day, and then displays it on a totaliser on the side, so you'll know when you need a top-up. £25, amazon.co.uk {5} Brita Fill & Go Get filtration on the go with this new bottle. It works by running the liquid through a carbon filter in the lid, which means you don't have to wait for it to drain through.
