YETI Rambler 20 oz Tumbler Stainless Steel — Blue Camo, Vacuum Insulated with MagSlider Lid

The YETI Rambler 20 oz Tumbler is a rugged stainless steel insulated cup with a MagSlider lid, built to keep drinks at their desired temperature while resisting dents, stains, and sweat.

Designed for everyday use — from the commute to the campsite — this 20-ounce Rambler combines double-wall vacuum insulation and YETI's durable Duracoat finish in a distinctive blue camo. It balances thermal performance, portability, and a secure magnetic slider to reduce sloshes, all while fitting standard cup holders and standing 6 7/8 inches tall.

How well does the Rambler 20 oz keep drinks hot or cold?

The double-wall vacuum insulation minimizes heat transfer, slowing the warming of cold beverages and cooling of hot ones. While exact times depend on ambient conditions and initial drink temperature, the Rambler maintains comfortable drinking temperatures significantly longer than single-wall cups.

• Double-wall vacuum insulation for reduced heat transfer
• Stainless steel construction resists temperature changes and impact
• MagSlider lid reduces exposure to air and limits spills while sipping

Is the MagSlider lid leakproof and easy to clean?

The MagSlider lid uses a magnet to close the drink opening, providing a simple barrier against splashes and heat loss. It is not fully leakproof, so it won’t prevent spills if tipped; however, the lid snaps apart for quick rinsing and is dishwasher safe for easy maintenance.

• Magnetic slider adds a quick on/off cover for the drinking area
• Not designed to be leakproof—avoid tipping or tossing in a bag without extra protection
• Dishwasher-safe components and straightforward disassembly for cleaning

How durable and portable is the Blue Camo Rambler?

Built from kitchen-grade stainless steel and finished with YETI’s Duracoat, this tumbler resists chipping, fading, and scratching from daily use. Its 3 1/2-inch lip diameter and 6 7/8-inch height are optimized to fit most vehicle cup holders, making it a reliable option for travel and outdoor activities.

• Duracoat finish prevents peeling and keeps the camo color vivid
• No Sweat Design keeps hands dry and prevents rings on surfaces
• Sized to fit standard cup holders for easy transport

What practical features should I expect for everyday use?

The Rambler 20 oz blends user-friendly details like a comfortable lip diameter, dishwasher-safe materials, and BPA-free construction. It’s made to be a low-maintenance travel companion that still performs under rougher conditions — from morning coffee runs to long days outdoors.

• BPA-free materials for safe beverage contact
• Dishwasher-safe for effortless cleaning
• No Sweat Design prevents condensation and improves grip

Who is this for? The YETI Rambler 20 oz in Blue Camo is ideal for commuters, outdoor enthusiasts, and anyone who wants a sturdy, attractive tumbler that keeps beverages near their preferred temperature. If you need a cup that fits cup holders, handles daily wear, and offers spill-reducing convenience without being guaranteed leakproof, this Rambler delivers dependable performance with a rugged style.
