Sidagar Ceramic Coated Insulated Coffee Tumbler 570ml - No Metallic Aftertaste, 6H Hot & Cold, Leak-Proof Vacuum Travel Mug for Home Office Commute

Write less. Taste more. Sip pure.

The Sidagar Fleeting Life Coffee Cup redefines your daily ritual with a 570ml insulated tumbler engineered for flavor purity and all-day performance. Its SUS31603 medical-grade stainless steel core — equivalent to SUS316L (Japanese standard) and 1.4404 (EN standard) — is fully encapsulated in a ceramic-coated interior liner that ensures zero metallic aftertaste, zero flavor transfer, and zero odor retention. Every sip of your latte, cold brew, fruit juice, or sparkling water tastes exactly as it should: crisp, clean, and uncompromised.

Proven Thermal Performance That Delivers. Engineered with advanced double-wall vacuum insulation, this tumbler passed rigorous GB/T 29606-2013 standard testing: filled with 95°C±1°C water and sealed, the internal temperature measured no less than 39°C after 6 full hours in a controlled 20°C±5°C environment. Separate ice-retention testing shows over half of ice cubes remain unmelted at the 6-hour mark. Hot latte stays steaming through your longest meetings; iced Americano stays crisp from your morning commute through lunch and beyond.

Everyday Design, Quietly Refined. The matte-finished body resists scratches, fingerprints, and daily wear, while the 360° leak-proof sealing system — triple-protected by a silicone sealing ring, safety locking buckle, and water-sealing stopper — keeps your bag, car, and desk bone-dry even when tipped or shaken upside down. A creative wide-mouth water-filling port lets you refill instantly without unscrewing the entire lid, saving precious seconds on busy mornings. The ergonomic contoured grip fits the natural curve between your thumb and forefinger for stable one-handed holding. A reinforced braided carry rope makes long-distance carrying effortless, and the silicon rubber anti-slip base pad provides silent, stable placement on any surface — no clanking, no sliding, no condensation rings.
