Astro 300 Headlamp

Engineered for minimalist backpackers, trail runners, and outdoor enthusiasts seeking reliable lighting without extra bulk, the Black Diamond Astro 300 headlamp balances intuitive single-switch operation with versatile power capabilities. Featuring a slim, low-profile housing that keeps weight close to the forehead, this headlamp minimizes bounce during dynamic movement on uneven trails. Powered by standard AAA batteries or the rechargeable BD 1500 Li-ion battery, it provides consistent flood lighting across variable trail conditions, sudden downpours, and cold evening approaches on mountain treks. You can buy this on our website, Makalu e-traders, or you can visit our physical store in Thamel.
