ThermoWorks - ThermoDrop® Zipper-Pull Thermometer

I like the size and the colour but you have to press very hard for a quite a while to turn it off. It’s a small, almost flat, button

Love being able to see the temp when doing outdoor activities. Like the hi low and the display flip so you can read it upside down.

Great little way to tell the temperature when waking up in the tent. Have it on my backpack zipper
