Ello Oasis 30oz Insulated Stainless Steel Tumbler — Twilight Blush, Retracting Straw & Leak-Proof Lid

The Ello Oasis 30oz Insulated Stainless Steel Tumbler with retracting straw is a leak-proof, cup-holder-friendly travel tumbler that keeps drinks cold for up to 24 hours. The Ello Oasis blends practical engineering with a streamlined aesthetic so you can carry one tumbler for work, commuting, and weekend adventures. Its unique retractable straw mechanism seals the lid when closed to prevent spills and keeps the drinking surface protected from dirt and debris. Constructed from insulated stainless steel and finished in Twilight Blush, this 30oz tumbler balances roomy capacity with a tapered shape that fits most cup holders.

How does the retracting straw prevent leaks and stay clean?

The Oasis uses a dial-activated straw that tucks completely into the lid, creating a sealed top that resists accidental spills. When closed, the straw is hidden from dust and pocket lint, keeping the drinking area hygienic between sips. Opening the straw is a quick twist, so you get convenient access without compromising protection.

• Dial-activated lid tucks straw fully into the lid for a sealed top.
• Closed position protects the straw from dirt and contact.
• Designed to remain 100% leak-proof when the straw is retracted.

Will this tumbler keep my drinks cold all day?

Yes — the double-wall insulated stainless steel construction helps maintain beverage temperature, keeping cold drinks chilled for extended periods. The 30oz capacity means fewer refills while still fitting in most cup holders. Insulation performance is optimized when the lid is used as intended to limit heat exchange and condensation.

How easy is the tumbler to clean and maintain?
