Chances are you recognize Stanley’s legendary vacuum-sealed thermoses—simple vessels like that probably shared trunk space with your grandpa’s old tackle box. They’re piping-hot outdoor classics, rising from humble Seattle origins to become a go-to for over 100 years worth of campers, soldiers, tradesmen, and coffee drinkers. Now fast forward to today, and they’re still using the same vacuum-insulated construction that’s made them famous in everything from their tough-as-nails tumblers to built-for-the-long-haul lunch boxes. Those guys who used the original Stanleys in 1913 would be proud.
