The rechargeable Cosmo 350-R features 350 lumens of power housed in a super compact, watertight body, making it perfect for urban adventures and overnighters in the woods. The Cosmo's new compact body is more ergonomic with a lower profile for improved balance, and the updated user interface includes a second switch for easy lens selection. Powered by the BD 1500 Li-ion battery that’s charged by a micro USB, the Cosmo 350 R also features a sustainably made elastic headband with Repreve recycled textiles. In addition, the updated optical efficiency not only provides brighter light, but also saves battery life. And thanks to its watertight construction, the Cosmo keeps lighting the way whether you're forced to bike home in the rain, or you're hiking back to camp in an unexpected downpour.
