From the YETI Rambler line, the 18oz Straw Bottle is constructed from durable and puncture-resistant stainless steel. The double-wall vacuum insulation will keep your water ice cold until the last sip. The leak-resistant straw cap is color-matched and includes a wide straw insert so you can get more water with each drink. The TripleHaul™ handle makes it easy to grab-and-go or hook onto your hiking backpack. When it’s time to clean, this bottle is top-rack dishwasher safe.
