The 34 oz bubba travel mug is designed for personal use, and is perfect for use at home, doing yard work, outdoor working on-site, at the beach, pool or lake. Holding just over a liter/quart, you can enjoy your favorite beverage longer without the need to refill. This size fits in most golf cart cup holders, and some larger car/truck cup holders. The built in bottle opener at the base of the handle makes a real multi-tasker.
