Take a "swig" of whatever fuels your day! Perfect for the golf enthusiast, the dimpled design really looks and feels like a golf ball! Thanks to our triple insulation technology, our best selling travel mug keeps drinks cold up to 9 hours and hot up to 3 hours. The cup holder friendly shape makes it the perfect travel companion, to and from the classroom, the conference room or even just your living room! This Swig includes a slide-closure lid to reduce messes while on the move and to maximize temperature retention. The straw-friendly opening can be covered with the slider to minimize spills when not in use. The slider is removable for easy cleaning and will snap back in place.
