The best part about summer 2021 has been taking my laptop to the roof and basking in the sun while I get some work done. The worst part has been witnessing the bottle of water beside me go from ice cold to lukewarm in 20 minutes flat. And listen, summer is my favorite season, so I’m completely willing to accept its pros—long days, great hair, block parties—along with its cons—sticky everything, the Mr. Softee jingle, the smell of hot trash. But drinking lukewarm water in 90 degree heat (with 80 percent humidity) is something I will no longer voluntarily do. I need an insulated water bottle that will keep my drink cold for the long haul.
