Key Features:

• Double-wall vacuum insulation design
• Leakproof flip-top lid construction
• Rust-resistant stainless steel body

Why Buy:

A vacuum flask for chai is more than simply comparing prices or choosing the highest capacity. A flask's usefulness throughout the day depends on insulation design, lid security, material quality and ease of carry. The Nayasa Expresso is the one for those who want a compact 425 ml option, whereas the Go24 pexpo, Milton Flip Lid and Perch Zenith are for larger capacities for extended use. The Cello Duro Metro adds another option with a practical flip-top design and an advertised temperature-retention period of up to 24 hours. Although several of these products advertise insulation lasting up to 24 hours, that figure should not be treated as a guarantee that chai will remain piping hot for exactly 12 hours in every situation. Preheating the flask with hot water, filling it appropriately and keeping the lid closed can help support heat retention. You can find these on Amazon at an affordable price. Shop now on Amazon.
