If you prefer a more civilized camping experience, this “Pint” vessel from Stable Goods Co. should be right up your alley.
The Pint easily converts from a canteen to a wide-mouthed pint glass/goblet by flipping it over and removing the bottom. The base can also be attached to the canteen spout to prevent tippage.
The product is made from double walled food grade stainless steel with a granite finish and is said to look and feel like ceramic but offer the durability of steel.
