A good flask can be a thing of beauty. But they accumulate dents and dings fast if your "leisure" activities have you scrabbling over craggy terrain, disappearing for weeklong trips into God-knows-where, or taking a cabin down to the studs and building it back up again. The folks at Stanley saw a solution – The Master Flask, made of their thickest 18/8 stainless steel. It withstands almost any punishment you can throw at it, holds 8-oz. of your drink of choice. Knurled top that even numb, frost-nipped fingers can grip. With a wide mouth for easy pouring and drip-free refills. Plus it's dishwasher safe, so there's no aftertaste when you switch from sinus-clearing white lightning to a more distinguished bourbon.
