Enjoying a beer outdoors is one of life's great pleasures. Instead of using flimsy plastic cups or fragile glasses, pour your next brew into one of these rugged glasses from Stanley. Made from BPA-free 18/8 stainless steel, they're hefty, dishwasher safe, and infinitely stackable so it's easy to keep several around, whether they're stowed in a camper, the back of a truck, or out on the patio. They also have double-wall vacuum insulation, so they're just as adept at keeping hot drinks warm as cold drinks cold.
