Took it to the gym this morning, filled with ice water, and it was still cold when I got home eight hours later. The double-wall build is solid and the satin finish gives it a nice grip.

Didn't expect the satin finish to feel this nice in hand, no slippery grip even when my palms get sweaty mid-set. Ice from last night was still rattling around after my morning run, which says enough about the double-wall insulation.

Filled it with ice water before a two-hour hike in July and there was still ice rattling around when I got back to the car. The double-walled steel doesn't sweat either, so my bag stayed dry.
