The Coldest Water 36 oz Insulated Tumbler Stealth Black — Leak-Proof, Triple-Insulated with Handle & 3 Lids

The Coldest Water 36 oz Tumbler with Handle and Straw is a fully leak-proof, triple-insulated stainless steel cup designed to keep drinks cold for over 36 hours or hot for up to 13 hours while offering three interchangeable lids for any sipping style.

Built around durable stainless steel and advanced insulation, this tumbler combines long-lasting temperature retention with a secure, 100% leakproof design. The set includes three lid options—sipping, flip-top and a thicker-drink chug style—plus a sturdy ergonomic handle and a non-slip base that fits most car cup holders. It’s styled for everyday carry yet engineered for demanding conditions, whether you commute, workout, or spend time outdoors.

How does the leak-proof system protect against spills?

The Coldest Water leak-proof tumbler uses precision-fit gaskets and a locking lid geometry to prevent liquid escape even when jostled. The manufacturing focuses on tight tolerances so lids seal reliably across temperature changes and repeated use.

• Three lid designs with sealed connection points for each use case
• Precision silicone gaskets engineered for dependable sealing
• Locking lid features that minimize accidental opening

How long will cold or hot drinks stay at the right temperature?

Thanks to triple-wall insulation and vacuum-sealed stainless steel, this tumbler maintains ice-cold temperatures for more than 36 hours and keeps hot beverages warm for up to 13 hours. That insulation reduces heat transfer from outside conditions and slows internal temperature equalization.

• Triple-insulated walls to limit heat exchange
• Vacuum seal between layers for extended thermal retention
• Stainless interior and exterior that resists corrosion and flavor transfer

Which lids are included and when should I use each?

The tumbler arrives with three functional lids so you can choose the best sipping method for the moment: a low-profile sip lid for everyday drinking, a flip-top for quick access, and a chug-style/blendinator lid for thicker shakes. Each lid snaps on securely and suits different beverages and activities.

• Insulated V1 Sip Lid — casual sipping and travel
• Flip Top V3 — fast access and one-handed use
• Chug/Blendinator — thicker drinks like smoothies or protein shakes

Will it fit inside my car cup holder and how comfortable is the handle?

The 36 oz size is designed with a tapered base that fits most cup holders—compatible with roughly 99% of common vehicles. The oversized ergonomic handle offers a comfortable grip for carrying full of ice or hot liquids, and the non-slip rubber bottom keeps the tumbler stable on flat surfaces.

• Cup-holder friendly tapered base for most vehicle consoles
• Large ergonomic handle for secure single-hand carrying
• Non-slip rubberized bottom to prevent sliding and tipping

Who is this for: The Coldest Water 36 oz leak-proof tumbler is aimed at people who demand reliable temperature performance and a spill-free experience—commuters, fitness enthusiasts, outdoor adventurers, and anyone who wants a versatile daily cup. It’s ideal if you need long-lasting cold or hot retention, multiple sipping options, and a durable, handled design that fits into everyday routines and travel.
