Our friends at Parks Project know a thing or two about what's cool and they get a gold star for this one! This glow-in-the-dark Nalgene earns its keep in your cupboard when it comes to versatility; not only does it conveniently keep you hydrated, since it glows in the dark, you can easily spot it around camp once the sun goes down, and it's super educational! Learn all about the Bortle Sky Scale and where you can find some of the best locations to view the night sky. If you're not familiar with the Bortle Sky Scale, it's a nine-level numeric scale measuring the night sky's brightness of a particular location to quantify the astronomical observability of celestial objects and the night sky. In simpler terms, it's a rating system that ranks the night sky based on how much light pollution is in the sky and how visible the stars are, the lower the number, the darker the sky. Glacier National Park is an International Dark Sky Park and has a rating of 2 on the Bortle Scale.
