The Yeti Rambler bottle with the Tortstork logo, what could be cooler? The Tortstork logo is engraved into the stainless steel bottle. Dishwasher safe. The cap is 100% leakproof and insulated with a 3-finger grip. The opening has an extra-wide opening for easy loading, drinking, and cleaning. Keeps cold drinks cold and hot drinks hot until the last sip. They are great for morning commutes to work and school. Fantastic for road trips and beach days. With a Tortstork logo on your Yeti, you will always have a conversation starter!
