12oz Stainless Steel Bottle - Sky Lily

The 30-hour cold retention is no joke—I took this to a day-long hike and my water was still icy at the end. It’s just the right size to fit in my car’s cup holder too.

I like that it’s leakproof and fits in my car’s cup holder, but the 12oz size feels too small for a full day out. It keeps drinks cold as advertised, though the insulation isn’t quite as impressive as I hoped for the price.

The 12oz size is perfect for my car’s cupholder, and the leakproof lid has held up fine so far. It keeps drinks cold for a long time, though I haven’t tested the full 30 hours. Just wish the bottle were a bit lighter for carrying around all day.
