The Stanley Easy-Fill flask has a narrow profile to slip easily in a pocket and a wide mouth.
When you can't take the whole bottle, the Stanely Easy-Fill Wide Mouth flask is the perfect solution. This flask is more narrow than a traditional flask, making it easier to slip into pockets, and the wide-mouth design makes it easy to fill without spilling a precious drop. Add in rugged stainless steel construction, and it's ready to go anywhere.
