The iDrink thermal bottle, black in color and with a capacity of 595ml (reference ID0555), is an insulated bottle for hot or cold beverages. Made of 304 stainless steel inside and out, BPA-free, with a double wall and vacuum insulation that keeps drinks cold for up to 24 hours or hot for up to 12 hours without spilling. Black is one of the most understated solid colors in this range of thermal bottles. It's a preferred option for those seeking a more discreet and neutral look than the animal-themed bottles in the same collection.
