The glow-in-the-dark Therm-o-compass RIDGE Ver.
A new luminous type has been added to the Therm-o-compass RIDGE Ver.
This product uses a phosphorescent material that absorbs ultraviolet light or light, stores energy for a certain period of time, and then emits light in the dark.
When light is absorbed, the electrons in the material are excited to a higher energy state, and over time they emit light as they return to their original lower energy state.
This light is emitted slowly, so it appears to glow for a long time in the dark to the human eye. It continues to emit light for up to 6 hours. (Manufacturer's nominal value)
It increases visibility inside a tent at night, so we recommend attaching it to pouches that you use frequently.

Introduction
This is the RIDGE MOUNTAIN GEAR version of the Thermocompass manufactured by Sun Company.
This set includes a compass and a thermometer that can measure temperatures from -30℃ to 50℃.
I always bring it with me on day hikes and overnight hikes.
It is useful to measure the temperature inside and outside the tent at night and keep a record of the temperature, clothing, and bedding.
