Without doubt our most useful accessory of the summer was Evie's beloved SIGG water bottle. Made from light-weight aluminum, each one has a unique BPA and phthalate free EcoCare liner so as well as keeping the drink super-fresh, it won't taint the flavour. It has a brilliantly designed nozzle which means it locks tight when you close the cap, so no pesky spillages (in fact it is guaranteed against them). They are so simple, slick and lovely to use (well, they are Swiss made by a company established in 1908) that there's something ultra-desirable about them. With over dozens of designs to choose from they are rather collectible too. We love.
