Keep beverages hot or cold for up to 24 hours with the 34-fluid-ounce Vacuum Flask from Esbit, offered here in black/red. Its BPA-free, 18/8 stainless steel double-wall construction provides durable insulation. The stopper screws tight to prevent any leaks and has grooves that make pouring a cup simple.
The lid doubles as an 8.5-ounce insulated mug, letting you sip away without scalding your hands. An extra 4.5-ounce plastic cup nests inside the lid, so you can share with a friend if you're so inclined.
