Zipper-Pull Hiking Thermometer by ThermoWorks

Nice simple and easy to use

This thing is great hanging inside my tent so I can keep track of the highs and lows throughout the night. It’s backlit, which makes it really easy to see at night. It’s very light weight and small

Super Nifty Thermometers

I originally bought 2, like them so much I bought 2 more. Great for hiking, biking, and other outdoor activities.

It works
