What Our Gearhead® Experts Are Saying:"I rely on the First Light Hybrid Hooded Jacket for cold-weather pursuits that don’t stop moving. Whether I’m skinning pre-dawn or navigating techy alpine terrain, the mapped insulation and breathable wool panels keep me just right without overheating."When we're moving in the mountains, we need a layer that can keep up with shifting temps and unpredictable output. The First Light Hybrid Hooded Jacket from Black Diamond nails that balance with mapped insulation and breathable merino paneling in a stretchy, low-bulk build that thrives under a pack or harness. This hybrid midlayer is built for dynamic pursuits—trail runs at altitude, dawn patrol skin tracks, or final pitches to alpine summits. The PrimaLoft® Gold Active insulation keeps warmth where we need it, while merino-wool-backed sleeves and underarms shed heat and wick moisture when we’re working hard. A slim fit, helmet-compatible hood, and packable design make this piece essential for anyone whose plans start and end in the cold and dark.
