Who it suits
Is it right for you?
Great for
- Two anglers sharing a carp session. There’s room for two XL bedchairs, tackle and the usual overnight clutter without feeling completely hemmed in.
- Anglers wanting a flexible front setup. Use the mesh, PVC or solid door panels, or roll the front right back when you want an open-front shelter.
Maybe skip if
- Mobile anglers carrying gear a long way. At 14.5kg before adding your beds, bags and tackle, it’s better suited to barrow-friendly swims.
- Solo anglers fishing cramped swims. The 330cm square footprint is a lot of shelter when you’re only using one bedchair.

Quick verdict
A cracking two-man home from home
The Fox EOS II Bivvy gives you and a mate proper space for two XL bedchairs, plus the weather protection and practical features you actually want on the bank.
It’s not a featherweight shelter, and the optional skin costs extra, but as a roomy two-person bivvy at the EOS end of the range, it’s a very sensible bit of kit.

The pram-hood design, full frame support, supplied accessories and solid waterproof fabric make this a well-equipped shelter.
The 8000mm outer, generous peak and choice of front panels give it useful protection across typical UK sessions.
It won’t catch fish for you, but the roomy, weather-ready base helps you stay organised and comfortable through longer bite-time sessions.
The supported frame and supplied pegs make setup straightforward, although the size needs a decent swim and a bit of planning.
It offers XL two-person space and a useful bundle of included extras without pushing into ultra-premium shelter territory.

The full rundown
Everything you'll want to know about the Fox EOS II Bivvy
Sharing a bivvy with a mate can go one of two ways. Either you’ve got a decent little base for a proper session, or you’re both tripping over bedchair legs while trying to find the kettle. The Fox EOS II Bivvy is very much aimed at avoiding the second scenario.
This is a roomy two-person shelter designed around two XL bedchairs. That’s the big selling point, mate. You’re not just getting a nominal ‘two-man’ label and hoping your gear magically shrinks overnight. There’s a proper 330 × 330cm footprint to play with, plus 185cm of headroom.
That extra space makes a difference when you’re doing a longer carp trip, especially if the weather turns and both anglers end up spending more time indoors than planned. You can get the beds in, keep bags tucked away and still have a bit of room to move without the whole shelter feeling like a tackle-bag cupboard.
The shape is a two-rib pram hood with a generous peak. In plain English, the front sticks out enough to give you useful cover around the doorway. That’s handy when rain is hammering down, but it also gives you somewhere to sort a rig, check the rods or have a quick brew without water running straight into the bivvy.
Full frame support comes supplied, which helps keep the structure properly supported once it’s up. That’s a nice touch for a shared shelter, as there’s more fabric and more span to keep tidy than with a compact one-man. Get it pegged properly and the whole thing should feel far more settled when the wind starts having a cheeky go.
The outer is 100% polyester with an 8000mm hydrostatic head rating. That’s a solid level of waterproof protection for normal UK bank weather, from steady drizzle to a proper bite-time downpour. As ever, pitching sensibly and using the supplied groundsheet matters. Water always finds the daftest route when a shelter’s poorly tensioned.
The front setup is nicely flexible. You get a two-way letterbox-style door with mesh, PVC and solid-panel options, so you can choose ventilation, a bit of visibility or more shelter depending on the forecast. The front panel also rolls back completely, turning the bivvy into an open-front setup for warmer sessions and better views of the lake.
Two front rod straps are included, which is a small feature but a dead handy one. They help keep rods organised when you’re getting settled or need to leave the fronts open. You also get heavy-duty pegs, a lightweight groundsheet and a zipped carry bag, so the basic package is ready to go rather than padded out with hidden extras.
There is one important extra-cost point. The optional 2-person skin isn’t included, and it adds 4.7kg if you decide to buy it. The skin can make sense for colder months or anyone wanting extra insulation and better condensation control, but factor that into the budget before you call the EOS II a complete all-season setup.
At 14.5kg including the groundsheet and pegs, this isn’t a stroll-across-the-field shelter. It’s a fair old lump, especially once two beds, sleeping bags, bait and tackle are loaded on the barrow. For a drive-and-barrel-to-the-swim session, though, that weight buys you space. If the swim’s tight, the footprint is the bigger thing to check first.

Our take
Big on space, sensible on the wallet
The real appeal here is simple: loads of room for two without turning your swim into a full-blown campsite. The generous peak, full frame support and front options make it flexible in everything from short overnighters to longer sessions.
The 8000mm waterproof fabric is reassuring for typical UK weather, while the supplied groundsheet and pegs mean you’re not immediately rummaging around for extras. Just remember that the optional 2-person skin is a separate purchase if you want extra warmth and reduced condensation.
Room to spread out
What you’re actually buying
The EOS II is a proper two-person XL bivvy, not a compact shelter with two sleeping spots squeezed into the marketing picture. Its 330 × 330cm setup size is designed around two XL bedchairs, with enough height to avoid feeling hunched every time you sit up.
The two-rib pram-hood shape gives you a generous peak over the front. That creates useful cover for the doorway and makes the shelter more practical when rain is bouncing off the lake. Full frame support is supplied, along with a lightweight groundsheet, heavy-duty pegs, two front rod straps and a zipped carry bag.
The 8000mm hydrostatic head polyester outer is built for wet-weather protection. Up front, the two-way letterbox door accepts mesh, PVC or solid-panel options. Roll the front away completely and you’ve got a more open setup for mild evenings, watching the water or keeping an eye on the rods.
Worth knowing. The optional 2-person skin weighs 4.7kg and isn’t included. It’s the extra to consider if you fish through colder months or want help with warmth and condensation, but it pushes the overall carry weight up again.
Pick your swim wisely
A shelter for shared sessions
This makes most sense for mates sharing a carp session, couples who want room for two beds, or anyone planning longer trips where a cramped bivvy soon gets a bit naff. There’s space for the usual bags and cooking bits, so you’re less likely to have a bedchair acting as your tackle shelf.
It’s especially handy on barrow-friendly venues where you can get the shelter close to the peg. The generous footprint is a benefit once you’re inside, but check the swim before unpacking. Narrow platforms, overhanging branches and tight margins can make a 330cm square bivvy awkward to place.
For warmer weather, rolling the front back gives you an open view and better airflow. In rain, use the PVC or solid panel for more protection. Mesh is the obvious shout when you want ventilation without inviting every flying thing in the county.
Worth knowing. Plan the layout before you fully peg it down. Put both beds where they need to go, leave room for the door and keep your rods clear of the front straps. A few minutes of faff at the start can save a proper shuffle when the rods are off.
The stuff you’ll want to know
Quick answers before you buy
Is it genuinely roomy for two? Yes. It’s designed to fit two XL bedchairs, and the 330 × 330cm footprint gives you considerably more breathing space than a tighter two-man shelter. You’ll still need to pack sensibly, of course. No bivvy can defeat two anglers, three carryalls and a mountain of bait.
Is it suitable for bad weather? The 8000mm waterproof rating, pram-hood peak, full frame support and choice of front panels give it a strong wet-weather setup. Pitch it square, tension the fabric and use the groundsheet properly. The optional skin is the add-on for extra warmth and condensation management.
Is it a good choice for short sessions? It can be, but the size and 14.5kg packed weight make it more shelter than you need for a quick solo overnighter. For two anglers sharing a longer session, though, the space starts to earn its keep pretty quickly.
Worth knowing. The best match is a venue where you can use a barrow or drop the kit close to the swim. If you’re doing a long hike with all your gear, a smaller one-man or compact two-man bivvy will be kinder on the legs.
