Lid is less secure than YETI's MagSlider.
YETI Rambler: Buy the YETI Rambler 20 oz Tumbler if you want the better-insulated, easier-to-clean tumbler with a magnetic lid that stays put.
Hydro Flask All Around 20 oz: Buy the Hydro Flask 20 oz All Around Tumbler if you drive with it, want a lighter cup and a lifetime warranty, and want to save $12.
Slightly. In Taste of Home's side-by-side, YETI edged out Hydro Flask by a small margin in both hot and iced coffee tests, and GearLab scored YETI's insulation 8.5 vs 7.5.
No. YETI says the MagSlider is not leakproof and won't prevent spills. Taste of Home found the Hydro Flask very leaky when held upside down, and it didn't recommend either tumbler for a bag.
Taste of Home found the Hydro Flask fit larger cupholders, while the YETI didn't fit securely in either size it tried. Hydro Flask lists a 3.43-inch diameter; YETI lists 3.5 inches wide.
As an Amazon Associate I earn from qualifying purchases. It never costs you more.
Every swap is a product sold in the US that does the main job of the original. Close match is another brand with similar features, Same brand, cheaper is an older, smaller or renewed model from the same maker, and Budget pick is the cheapest thing that still does the job. On each page, Closest match is the close match nearest the original in price, and Lowest price is the cheapest swap. We compare published specs, retailer listings and reviews; we don't test products ourselves.
A cheaper product is cheaper for a reason. Each swap says what you give up, like weaker noise cancelling, a smaller screen or a shorter warranty, so you can decide if the savings are worth it.
Prices are typical US prices from retailer listings and price trackers, last checked October 2026. They are not live Amazon prices, which change often. When a price couldn't be confirmed, the page says “Check price on Amazon” instead of showing a number.
