Since once-in-1,000-year heatwaves now seem to occur over large parts of the country every other Thursday or so, you need a water bottle that can keep your drink ice cold all day long, even in brutally hot conditions.

Waves Gear’s Forever Cold has been a popular option for years, because its double walled stainless steel construction can keep cold drinks cold for 24 hours straight, while still feeling comfortable to the touch on the outside. It’s certainly not the only water bottle like this, but it’s one of the few that goes the extra mile by including a double walled stainless steel cap as well. The plastic lid included with most steel bottles is, thermodynamically speaking, basically a gaping hole allowing environmental heat into your cold drink, and in my experience, the metal cap really does make a difference.
