Available on Amazon.com – Sun Company Brrr-ometer – Snowsport Zipperpull Thermometer | Skiing & Snowboarding Thermometer for Jacket, Parka, or Pack
The Brrr-ometer can attach to a jacket, sleeping bag, backpack, etc. and is a convenient way to check the temperature. It’s accurate and the build quality is nice. I checked it side-by-side with other thermometers to confirm that it accurately reads the temperature. I use this thermometer while backpacking. #Brrrometer
