Clima Bottle | Borealis - 500 ml

Left it in the car on a 30°C afternoon and came back two hours later to water that was still properly cold—that insulation really holds up. It’s become my go-to for the commute, and the 500 ml size fits perfectly in my bag without being bulky.

I took this bottle on a hike in 35°C heat and nearly six hours later there were still ice cubes floating in my water. The double-wall insulation really does its job.

I was skeptical about how long it would really stay cold, but after three hours in my backpack on a hike, the water was still refreshingly cool. The mouth opening is just wide enough to add ice cubes easily, which makes a big difference for me.
