Frontier II keeps everything that worked before and brings new enhanced performance, smarter features, and greater convenience across the board. Available in Green or Camo and three sizes; Frontier II, Frontier II X, and Frontier II XL, this next-generation bivvy delivers serious upgrades in usability, protection, and setup speed.
What’s new:
• The ETS BOSS (Easy Tension System) is now a geared system that prevents frame collapse during setup and makes erection smoother than ever. A refined release trigger on the ETS block streamlines breakdown and storage. We’ve fitted new sprung-loaded, keyed elbow joints with ergonomic grips ensure a faster setup.
• We have widened the front door for better visibility and access, added mozzy vents either side of the front door on all models and included a Zip-in Groundsheet for easier attachment, complete protection, and direct connection to the optional Inner Mesh Shield (X & XL models only).
• Now all models feature four all-weather vents per model, all accessible from inside with camo mozzy mesh and pegging options to maintain airflow in rain. We’ve added storage points with two extra hanging hooks by the door complement the four mesh pockets and central hook.
• A new quick-release cam system has been fitted to the supplied Heavy Duty Storm Pole.
• The Vapour Peak now comes supplied as standard with every model, no need to buy separately.
• All three bivvy sizes launch with a full suite of optional extras, including: Camo Mozzy Mesh Front Panel (now with letterbox-style door), Deluxe Wrap – Extends coverage by 60cm, fits two bedchairs converting Bivvy into 2 person shelter, and features aligned vents, storm pole points, and easy Velcro + D-Loop attachment. Deluxe Extension – 1.5m extension at the front now with full bivvy coverage for twin-skin insulation and reduced condensation. Four removable rear panels convert it into a cap when needed.

Water ingress or excessive condensation.
Verify the groundsheet is securely zipped in and properly sealed. Ensure all vents are open to some degree for airflow. Check the Vapour Peak is correctly fitted. Make sure storm cords are taut during heavy rain.
Zips are stiff or difficult to use.
