18oz Stainless Steel Sports Bottle - White

I was skeptical about the 24-hour cold claim, but after leaving it in a hot car for a full workday, the water was still ice-cold. The double-wall insulation really does its job, and the 18oz size fits perfectly in my bike’s cup holder.

Took this on a long hike yesterday and the water was still ice-cold after eight hours in the sun. The double-wall vacuum insulation really does its job, and the 18oz size fits perfectly in my backpack's side pocket without adding much weight.

The lid design is a bit awkward to drink from without spilling, but the double-wall insulation definitely keeps my water cold for the whole workout. It’s a solid bottle, just not perfect for one-handed use.
