ThermoLock Classic : 24Hr Hot & Cold Steel Flask (Silver)

Locks in the temperature, for a full 24 hours. ThermoLock Classic is a double-wall vacuum steel flask built to seal your drink at the temperature you poured it, hot chai stays hot and cold water stays icy, right through the day. A leak-proof lid means it rides safely in any bag, to office, school, gym or the hills. This classic silver finish comes in two sizes, so there is one for every bag.

• 24 hours hot or cold: double-wall vacuum insulation holds your drink's temperature all day and night.
• ISI-certified food-grade steel: made from ISI-certified (IS 17526) food-grade stainless steel, safe, hygienic and rust-free.
• Leak-proof lid: a screw-tight lid seals fully, so it travels in a bag without a drop escaping.
• Double-wall build: stays dry and comfortable to hold, with no sweating outside and no heat on your hand.
• Two sizes: choose 500ml for a light carry or 1 litre for a full day out.

One flask, all-day temperature, wherever the day takes you.
