Completely redesigned, the FirstLight Tent is Black Diamond's optimal shelter for serious mountain missions. It's still the lightest, most packable tent that Black Diamond builds, and it's been updated to maximize airflow while still minimizing weight. Black Diamond's new (patent pending) Flow Manifold technology allows interior heat convection and exterior airflow to draw moisture vapor out of the tent, so you don't have a crisp layer of frost on your sleeping bag every morning. Flow Manifold also allows for a central, ceiling exit for anchoring in on steep mountaineering expeditions. Made with Dyneema, the guylines are significantly stronger than the previous season's FirstLight, and the internal pole grips are reinforced for better longevity.
