Small enough to bring just in case, but bright enough to light the way down unexpected rappels and dark trails, the new Astro175 features an updated compact body that is more ergonomic, with a lower profile for better balance. In addition, the updated optical efficiency not only provides brighter light at 175 lumens, but also saves battery life. The Astro's dimming and strobe modes let you customize the lighting to your needs, and the highly weather-resistant housing shrugs off rain and snow.
