42oz. 保冷套（適用於42oz. 塑膠瓶）

The grip is just right—not too tight, but my bottle stays put on the car seat. I grabbed the green one for hiking, and it’s kept my water ice-cold for hours without any sweat on the outside.

I love that it comes in different colors to switch up the look each day, and my water stays ice-cold for hours without any condensation.

Finally, no more wet hands from condensation on my 42oz bottle—this sleeve keeps the outside dry and my water cold for hours even in the sun.
