DetailsWith 1-full sized tumbler and measuring in at 375ml, the Firelight 375 keeps your favorite cocktail at the perfect temperature all day long. Designed for your rough and tumble lifestyle, it fits easily into your purse or backpack. It’s vacuum insulated, leak-proof, with a brushed stainless steel construction and the 6-shooter tumbler magnetically attaches to your flask. Half for you, half for me… Why is it 375ml? Because drinking is better with friends. The Firelight 375 is built exactly for ½ a bottle of wine or liquor. So open your favorite single malt, split it between 2 Firelight 375’s, and meet your drinking buddy outside for some conversation and cribbage.
