The Prologic C-Series 2 Man Bivvy is built around an ultra-stable, easy-fold two-rib frame, making it a lightweight and straightforward shelter to assemble. Its optimised interior offers generous space for two carp anglers, leaving room to organise gear without compromise. The front door uses two-way zippers, so it can be set in a letterbox configuration to keep an eye on fish activity while staying sheltered in poor weather. This setup also boosts internal airflow when paired with the large rear mosquito mesh-covered ventilation window. On warm summer days and nights, the front doors and side can be fully opened and pinned back for panoramic views and a comfortable climate.
