This mug is called a "Classic" for a reason - and not just because the keg shape brings back memories of past toga parties. The 52 oz. bubba Classic Insulated Mug is just as perfect for a hot coffee as it is for a cold beer, thanks to dual-wall foam insulation that keeps drinks hot for up to 3 hours or cold for up to 12 hours. The dual-wall foam insulation also protects your mug from any external sweating; that plus the side handle means fewer drops and fewer party fouls. With an extra wide base, your Classic Insulated Mug is ready to withstand any accidental tips, protecting your precious drink at all costs. Even if this mug does get knocked to the ground after the boat takes a sharp turn, the tough, durable exterior is strong enough to resist shattering. When you feel the first hints of thirst coming on, just flip the top lid open for easy drinking; you'll barely have to look up from your lounge chair. For added peace of mind, all bubba products feature a lifetime guarantee.
