I discovered Big Frig through Black Rifle Coffee Company. BRCC sells some Big Frig products with BRCC branding, such as their "Coffee Saves" 30-ounce tumbler, which I use daily. This 128-ounce Big Frig growler is just as awesome. I use it to "administer" a gallon of coffee to my fellow runners and walkers after we cover 10-21 miles on a Saturday morning. They love that the coffee is still hot and fresh up to five hours after I have brewed it and poured it into this growler. I love that this growler means that I don't have to drag a coffee maker to the park where we meet. I also love the screw-top, flip-open (as in, "can't-be-lost") pouring cap, which means that I don't have to open the larger cap -- thereby keeping the coffee hot and avoiding spills that would occur from pouring from the bigger mouth. ONE TIP: When you seal the larger cap against this growler, rotate it clockwise as tightly as possible so as to avoid secondary dribbles past its silicone seal when you pour from the smaller opening.
