Caffeine. For most guys, it’s the fuel that gets jobs done. You can keep your preferred caffeine delivery system (say, coffee) hot for up to 17 hours or icy for more than TWO DAYS by putting it in this vacuum-insulated mug. Made of food-grade 18/8 stainless steel with a sturdy, leak-resistant BPA-free cap, it holds a whopping 20 oz. of beverage for a long stint of sipping between refills. Wide mouth swallows up ice cubes and makes for easy cleaning. Fits in the cup holder of your truck or backhoe and goes right into the dishwasher with no fancy hand washing or drying required. Drink up!
