The YETI Flask is constructed with kitchen-grade stainless steel and fits 7 oz of your choice of liquor. The curved design allows for easy fit into any pocket and the Duracoat™ colors will not peel or crack. Use the stainless steel funnel to pour in your drink and easily twist on the cap for a leakproof seal. When the day is done, place your flask on the top-rack of the dishwasher for easy clean-up.
