Zipper-Pull Hiking Thermometer by ThermoWorks

Great product. I bought this one to replace the one on my edc bag and I'm glad to see they improved the battery retention. My old one kept turning on and off at random.

Small and easy to read

Glad I bought it! This little thermometer is helping me dial in my layering and sleep systems for multiple winter treks. Like how the numbers re-orient so its essy to read. Good high/low and battery saver features.
