LEISURE TIME COFFEE 316 Stainless Steel Portable Advanced Portable Vacuum Cup

Engineered with a medical-grade 316 stainless steel inner liner, this LEISURE TIME COFFEE vacuum cup eliminates metallic taste transfer while delivering reliable thermal retention for your daily caffeine routine.

The double-wall insulation maintains liquid temperature between 6 and 12 hours, making it suitable for extended commutes or outdoor activities. An integrated intelligent temperature display removes estimation; pressing the sensor reveals the exact internal water temperature on the exterior interface, preventing burns and ensuring optimal sip readiness. The secure locking cap works alongside a durable rope handle to prevent accidental spills when stored in bags or mounted to bike frames.

A thickened 304 stainless steel outer shell provides structural rigidity against impacts, while the 450 ml interior capacity balances full servings with compact portability. Matte finishes in Smoke Brown, Wine Red, Blue, Black, and classic Brown offer corrosion-resistant surface protection alongside a clean profile that fits professional and casual environments equally well.
