Keep your tent or campsite illuminated after the sun goes down with Black Diamond's Remoji Light. The Remoji easily attaches to the roof of your tent or on your hammock straps so you can have some reading light late at night. A lithium battery easily hooks into a USB cord to recharge the light once you're back home, and an IPX4 waterproof rating will handle light rain or if it accidentally takes a quick dip into the water.
