For the all-purpose mess kit, you won’t need much more than the 20 oz. Enamel Mug: brandish it over an open fire to cook your beans, polish it off for the morning's oatmeal or cold cereal, and fill 'er back up with some hot coffee. Produced by our legendary enamelware manufacturer in the EU, the 20 oz. Enamel Mug has an interior volume scale, helpful for measuring out portions, and stays comfortable in the hand without feeling oversized. As with all our enamelware, boil water or reheat last night’s scraps by throwing the Mug directly over open flame - a quick rinse and it’s ready to go back in the pack.
