The Outdoor Research Helium UL Vestibule is a lightweight, waterproof extension designed exclusively for the Helium UL Bivy. It provides additional gear storage and weather protection for fast-moving backpackers and minimalist adventurers without adding unnecessary bulk.
Made from durable 15-denier ripstop nylon with a silicone coating, the semi-translucent vestibule delivers reliable waterproof protection while keeping weight to a minimum. Its barrel attachment system connects securely to the Helium UL Bivy, while reflective details improve visibility in low-light conditions.
Designed for use with a single trekking pole, it includes an aluminium stake and two stake loops for a stable, efficient setup.
