- Stanley Unbreakable Flask
Stanley Unbreakable Flask
Sleek design meets superior, unbreakable construction in our toughest flask yet. It’s engineered with cold-rolled steel and finished in the perfect Foundry black powdercoat. The ergonomic shape also slides easily in your hip pocket for anywhere adventuring. Internal threads on the cap make for smoother sipping or swigging, and the wide mouth allows for easy refills.
