Balance Athletica Element Bottle (£33)
"Give the gift of hydration with this nearly one litre water bottle! This is my daily water bottle that is easy to find in my large bag, due to its colourful print, and it keeps my water cold for hours. One of my favourite things about it is that it doesn't leak, so the water actually stays in the bottle instead of dripping from the straw." — Angelica Wilson, associate editor, Fitness
