ThermoWorks - ThermoDrop® Zipper-Pull Thermometer

Whether you're headed out for your next adventure or just keeping tabs on things at home, nothing beats the accuracy and versatility of ThermoDrop for ambient temperature tracking. Easily attaches to your coat, backpack, or inside your fridge.
For all of your ambient temperatures on the go, you need ThermoDrop (patent pending). ThermoDrop attaches to your jacket zipper or any place you can attach a key ring. Small enough so that it can be placed inconspicuously but big enough to do the job well. The auto-rotating display and big digits mean you can read the temperature from any angle. Whether hiking, biking, skiing, camping, or just out for an evening stroll, ThermoDrop gives you the temperature of the great outdoors. It will even tell you how cold it got overnight with the Max/Min readings. And, with the IP67 rating, you are protected from splashes and unexpected rain showers. ThermoDrop is perfect for indoor temperatures too! Hang in fridges, freezers, or anywhere you need an ambient measurement.
