Product Details and Uses

Prologic Fulcrum Session Bivvy & Overwrap

The Ultimate Home-from-Home: Maximum Space, Unrivalled Protection.

At Gerry’s, we know that session angling is as much about endurance as it is about skill. The Prologic Fulcrum Session Bivvy is engineered for the long-haul angler who demands a spacious, rock-solid base of operations. Built around an oversized 20mm diameter, three-rib aluminium frame, this bivvy offers incredible structural integrity and wind resistance, ensuring your “home” stays pinned to the bank when the weather turns brutal.

Constructed from the same high-tier 210 double-coated fabric found across the premium Fulcrum range, it boasts a 10,000mm hydrostatic head. This system is supplied as a complete package, including a full overwrap and an internal sleeping capsule, making it one of the most versatile and protective long-stay shelters on the market.

Why the Fulcrum Session is a Gerry’s Top Pick:

  • Heavy-Duty 20mm Frame: While most bivvies use 16mm or 18mm poles, the Fulcrum uses 20mm lightweight aluminium for maximum rigidity and longevity.

  • Pro-Vent 360-Degree System: This advanced ventilation setup allows for constant air exchange. By keeping the air moving, it significantly reduces condensation and keeps the internal temperature comfortable in the summer.

  • Zipped-In Pro-Tect Groundsheet: The heavy-duty groundsheet zips in 10cm above ground level, creating a “tub” that prevents surface water, mud, and insects from entering your living area.

  • Fully Enclosed Inner Capsule: Includes a mosquito-meshed internal compartment, allowing you to seal yourself off entirely from bugs while maintaining perfect airflow.

  • Full Overwrap Included: The supplied overwrap creates a “twin-skin” effect, dramatically increasing heat retention in winter and creating a small porch area for extra storage.

Key Performance Advantages

1. Incredible Headroom & Depth:

Standing at 180cm tall, the Fulcrum Session allows most anglers to stand upright inside. The deep 330cm footprint provides enough room for two wide-format bedchairs with a central aisle, or a single angler with an abundance of gear for a week-long stay.

2. The “Twin-Skin” Advantage:

By using the included overwrap, you create a layer of “dead air” between the bivvy skins. This acts as a thermal barrier, keeping the heat in during the winter and reflecting the sun’s rays in the summer to keep the interior cool.

3. Pest-Free Comfort:

The combination of the zipped-in groundsheet and the internal mesh capsule makes this bivvy virtually “impenetrable” to spiders, mosquitoes, and rodents. It provides total peace of mind for those fishing in heavy undergrowth or on wild European venues.

4. Quick and Easy Assembly:

Despite its massive size, the three-rib pram-hood design is intuitive and fast to erect. The oversized poles slide together effortlessly, and the full tension bar set ensures the fabric is drum-tight every time.


Gerry’s Verdict: This is the definitive ‘Session’ bivvy. The 20mm frame gives it a ‘tank-like’ feel that inspires total confidence. If you’re planning on doing week-long trips or taking a partner along, the Fulcrum Session provides the luxury and protection you need to fish at your best
