Katabatic Gear Bristlecone Bivy

The Katabatic Gear Bristlecone Bivy pairs a waterproof floor with a water-resistant (not fully waterproof) upper, a mesh window for airflow, and a long U-shaped zip that makes entry and exit easier than a bivy with just a small top opening. Full bug netting keeps insects out even when there's no tent wall overhead. Since the upper only resists water rather than blocking it outright, the Bristlecone is built to sit under a pyramid shelter or tarp for actual rain protection, not to stand alone in a downpour. That tarp-plus-bivy pairing suits hikers after a floor and bug barrier while keeping the overall shelter weight down.
