マーベル タンブラー

Took it to the beach and the ice was still rattling around 9 hours later, which honestly surprised me. The triple insulation really does its job, and the stainless steel feels solid without being heavy.

Filled it with iced coffee before an 8am meeting and it was still cold when I left the office around 5. The triple insulation really does hold up, and the stainless steel exterior hasn't picked up a single scratch in my bag.

Took this on a hike last weekend and my water was still cold when I got back to the car, which never happens with my old plastic bottle. The triple insulation really does what it says.
