Fans of American brand <a href="http://www.selfridges.com/GB/en/cat/bobble/" style="text-decoration: none"><font color="black"><b>Bobble</b></a></font>’s filtered water bottles will love the new <b>Insulate bottle</b>, a versatile stainless steel vessel that will keep beverages hot for up to 12 hours or cold for up to 24. With a leak-proof seal to prevent unfortunate spills, the double-wall construction helps prevent condensation so your bottle doesn’t sweat in your bag.
