DeepDish Plates and Bowls are designed to nest with most MSR cook systems and pot sets, and make a great addition to any outdoor kitchen. Their highly functional shapes are made from hot and cold-safe polypropylene and color-coding matches with our mugs and utensils to help everyone keep track of their own set. MSR Pot Compatibility: Small nests inside 2.5 L pots (Quick™ 2 & Base 2), Medium nests inside 3.2 L pots (Flex™ 3), Large nests inside 5.3 L (Flex™ 4) pots, and the Bowl nests inside the Trail Lite Duo Cook System, and outside the Reactor 1.7 L pot.
