Coghlans's Fold-a-Cup is just a great piece of design, the cup folds in half into itself for easy stowing. Not the biggest cup in the world though.
Coghlans says: Durable crushproof plastic cup. Convenient to carry in pocket or pack.
Coghlans's Fold-a-Cup is just a great piece of design, the cup folds in half into itself for easy storing. Not the biggest cup in the world but just enough for a quick cuppa. Ultralighters might want to drink out of their own cooking pot but it's nice to have a separate mug - and often more convenient - this one weighs about an ounce so it won't slow you down.
Cheap, light, durable (have had one for 8 years and it's almost like new). Can handle boiling water. Your tea/coffee stays warmer for much longer than in a single walled metal cup. I never leave home without it. A true classic.
