  • Best for: Solo anglers and regular carp fishers who need extra sheltered space
  • Not ideal for: Those seeking a full bivvy replacement or integrated groundsheet solution

More usable living and storage space - with an overwrap that expands the floor area

Attaches around the Particle 1 Man Bivvy to increase internal footprint, creating extra covered floor space. The added enclosure acts as an extension rather than replacing the original bivvy.

Allows chairs, tackle boxes and clothing to sit under cover without cluttering the main bivvy area, improving comfort on multi-day sessions.

Stay dry in heavy rain - thanks to 5000mm HH waterproofing

Manufactured from fully waterproof material rated at 5000mm HH, which prevents water ingress under sustained rainfall. The outer layer sheds water while forming a protective barrier.

Keeps sleeping and storage areas dry during prolonged wet weather, reducing the risk of soaked kit and uncomfortable nights.

Better airflow and insect protection - with removable front panel and mozzie windows

Includes a removable front panel plus mozzie windows and a large rear window, while tension straps and bars secure a snug fit. Ventilation points allow airflow without leaving openings for insects.

Provides airflow that helps reduce condensation while keeping midges and small insects out, making longer stays more pleasant.
