(3 pack) Ozark Trail 30 oz Stainless Steel Insulated Tumbler with Swivel Lid, Black

This model is my husband's favorite water bottle and he keeps one with him all day, and another next to the bed at night. At half the price of the major brand's almost identical “Ice Flow” beverage container, it's a steal. And the handle is wider making it more comfortable for a man's hand. This one is well insulated, it still has ice 24 hours later on his nightstand! He just adds more ice each night then runs it through the dishwasher a couple of times a week. In 5 years and half a dozen tumblers, there has only been one time there was some black gunk (on the straw) but it was a bottle that was left in the hot garage for several days. By the way, when closed this tumbler is 100% leak free.
