Coffee and tea drinkers rejoice - lukewarm drinks are now a thing of the past! The 18 oz Wide Mouth Hydro Flask with Hydro Flip Lid will keep your coffee and tea steaming hot for up to 12 hours, or your cold beverage icy cold for up to 24 hours. The 18/8 food-grade stainless steel interior is non-porous, meaning no residual bacteria buildup and no hints of yesterday's flavored latte. The BPA-free, PP#5 flip lid provides quick and easy one-handed access and the smartly designed rubber stopper plugs the opening and prevents spills when not in use. Hydro Flask's 18 oz Wide Mouth bottle, like all Hydro Flask products, is made from environmentally friendly materials, is 100% recyclable and toxin free, and is backed by a lifetime warranty. Look for the H-guy and Hydro Flask logo to ensure you're getting the market's premium insulating beverage bottle.
