The classic design of the Swiss < a href="http://www.selfridges.com/en/sigg/" style="text-decoration: none"><font color="black"><b>Sigg</b></font></a> <b>bottle</b> gets a bold makeover in glossy neon pink, with the easy-carry screw top now in maximum-contrast white. Made from a single piece of high-grade aluminium, this light and robust bottle stays watertight, even with carbonated drinks.
