Turn compatible YETI Rambler drinkware into a practical cocktail shaker for the campsite, patio, tailgate, boat, or home bar with the Rambler Cocktail Shaker Lid. This stainless steel accessory installs on select Rambler vessels, letting you use drinkware you may already own as the insulated base of a portable shaker. Its easy-press design provides a secure, leak-resistant fit while you mix, and the threaded 1-ounce cap twists off when it is time to pour. A built-in strainer helps hold ice inside the vessel, allowing the mixed drink to flow into a serving glass without requiring a separate bar strainer. The kitchen-grade 18/8 stainless steel construction is puncture- and rust-resistant, while double-wall insulation and YETI's No Sweat Design help maintain a cold mixture without leaving the outside covered in condensation. Compatible vessels include the Rambler 10 oz Lowball, 10 oz Stackable Mug, 20 oz Stackable Cup, 24 oz Mug, 25 oz Straw Mug, and 20 oz Tumbler; the vessel itself is not included. The lid is intended for preparing cold drinks and should not be used to shake hot liquids because internal pressure can cause the cap to leak or eject. Carbonated beverages should also be avoided for the same pressure-related reason. When the drink is ready, the cap and lid provide a straightforward transition from vigorous shaking to controlled pouring, making the setup convenient for preparing cocktails away from a fully equipped kitchen. All components are dishwasher safe for uncomplicated cleanup after use. Durable materials, an insulated design, and broad compatibility across several popular Rambler formats make this shaker lid a useful addition for anyone who wants compact barware that travels easily and works with existing YETI drinkware.Specifications and Features: Converts compatible Rambler drinkware into a cocktail shaker 18/8 stainless steel construction Double-wall insulation with No Sweat Design Leak-resistant easy-press lid 1 oz twist-off cap and built-in strainer Dishwasher-safe components For cold, noncarbonated drinks only Color: Stainless Steel Brand: YETI Series: Rambler Product Type: Cocktail Shaker Lid Manufacturer Part Number: 21071501989 UPC: 888830275030
