Insulated Flask 500ml

The double-walled steel really works, no metallic aftertaste at all. Took it on a hike and my water was still cold hours later. The 500ml size fits perfectly in my bag's side pocket too.

Filled it with hot tea at 7am and it was still steaming at lunch. The 500ml size fits perfectly in my backpack side pocket without leaking.

It’s been three weeks of daily use and the double-walled steel still doesn’t hold any smell from yesterday’s tea, which honestly surprised me. Ice water stayed cold through an entire afternoon hike, and the 500ml size fits perfectly in my car cup holder.
