Stainless Steel Tumbler Vacuum Flask 2000ml

Filled it with ice water before a 6am hike and there was still ice clinking around at dinner. The 2000ml size means I'm not constantly refilling, though it's definitely too big for a cup holder.

I’m a bit of a cold-coffee skeptic, but this flask actually kept my brew scalding from my 6 a.m. shift all the way to a lunch break in the field, which stunned me. The 2000ml capacity means I don’t have to ration a sip, and the industrial look fits right on my truck’s console without feeling fragile

Took this on a two-day camping trip and the 2000ml size meant I didn't have to refill constantly. Kept my coffee hot through the second morning, though it's honestly a bit heavy once it's full.
