Yes, the Instagram-friendly Glacce Crystal Elixir Water Bottle (£74) is a little bit pricey. However, not only is it eye-catching (making it harder to misplace), but it also has energising crystals inside each bottle to take on the go with you. Plus, with water dispensers out of action inside gyms, it would be rude not to invest in a quality water bottle like this — available in clear quartz, rose quartz, smoky quartz, black obsidian, and amethyst.
