Although designed for the Pathfinder Canteen cup, the Pathfinder Stainless Steel Cup lid fits most military type canteen cups. It is made from 304 stainless steel, has three straining holes on one end, and a "D" ring that will stand up by itself. This is a great addition for many military type canteen cups. Note, it does not fit the old 1950's/60's model with the handle that folds underneath the cup (Cup NOT Included).
