Product details

Bamboo Vacuum Flask — 500 ml

A 500 ml double-wall vacuum flask that holds hot or cold for around 24 hours.

Pour boiling chai at 8 am and it's still warm the next morning; ice water stays cold just as long. The structure is food-grade stainless steel — that's what your drink touches — wrapped in a real bamboo sleeve for the warm look and feel. Leak-proof steel cap. Black or white, both with the bamboo sleeve.

Stainless body, bamboo sleeve. Hand-wash the inside; wipe the sleeve, don't soak.

Three things make it work.

01

Steel inside, bamboo outside

The interior is food-grade stainless steel — that's what your drink touches. The exterior is a real bamboo sleeve over a stainless body. Bamboo gives it the warm feel and natural look; steel does the work of keeping the drink clean.

02

Double-wall vacuum insulation

The wall between the inner and outer steel is vacuum-sealed for thermal retention. Holds temperature for around 24 hours either way — best-in-class for a 500 ml flask.

03

Leak-proof steel cap

Stainless steel cap with a leak-proof seal. BPA-free, non-toxic, rust-free. Pours clean; doesn't drip down the side after a sip.

A flask that actually keeps temperature.

🌿

Hot at 9 am, still hot at 9 pm

Double-wall vacuum insulation holds temperature for around 24 hours either way. Morning chai is still warm in the evening; iced lime water at 9 am is still cold at 9 pm.

🌿

Long commutes & travel

For people whose day starts at the breakfast table and ends in another city. The flask is built for routes, not just rooms.

🌿

Office desk water

Cold water that stays cold without dragging out the freezer tray every refill. Steel inside, bamboo outside — sits warm in the hand even when the water is freezing.

🌿

Outdoor & trail

Holds up to a day of trekking, picnic, road trip. The leak-proof steel cap and the double-wall body do the work — no fragility, no spillage.

Where it fits your day

On the trail

On the trail

A day of trekking, one flask. The double-wall body shrugs off bumps and the steel cap holds tight in a packed rucksack.

Through the airport

Through the airport

Fill up before security or after, and it holds till you land. One bottle from the cab to the gate to the city.

A closer look

Chai at 8, still warm by evening
01 — Mornings

Chai at 8, still warm by evening

Fill it with boiling chai before you leave the house and it holds that warmth for close to a full day. No reheating at the desk, no lukewarm last sip. The double-wall vacuum body does the work while the bamboo sleeve stays warm in your hand.

Built for routes, not just rooms
02 — On the move

Built for routes, not just rooms

For the days that start at the breakfast table and end in another city. Tucked into a bag, the leak-proof steel cap stays sealed through every bump and turn. Hot or cold, what you poured in this morning is still right hours and miles later.

Cold water, all day, no fridge runs
03 — At the desk

Cold water, all day, no fridge runs

Pour ice water in the morning and it stays cold till you log off, so there's no walking to the cooler every hour. The steel interior keeps the water clean-tasting, and the bamboo sleeve sits warm and dry in your hand even when the water inside is freezing.
