The Eureka! NoBugZone 3-in-1 Shelter offers customizable protection from biting insects, burning sun, and a passing shower. The separate, waterproof rain fly shrugs off a light sprinkle, or remove the fly entirely for added ventilation through the all mesh roof. The near-vertical sides provide ample shade and more interior space. The no-see-um mesh provides plenty of ventilation while defending against the tiniest critters.
