Product Information
The Fox Frontier II is a bivvy with a lightweight aluminium frame and a high, flat-backed shape that gives you maximum headroom and usable internal space. Its khaki VenTec fabric has a blackout laminate lining and a 20,000mm hydrostatic head.
The geared ETS BOSS system helps prevent the frame collapsing while you put it up, while sprung-loaded keyed elbow joints with ergonomic grips speed up the job.
Four all-weather vents can be opened from inside and use camo mozzy mesh, with pegging points to keep air moving in rain.
A widened front door, zip-in groundsheet with entry flap, three door panels and four internal mesh pockets cover access and storage. The supplied Vapour Peak, Heavy Duty Storm Pole and double-zipped carry bag complete the package.
Fox Frontier II Review
The Fox Frontier II is the new version of one of Fox's most popular bivvies, and it's had a proper rethink. Fox have kept the lightweight aluminium frame but given it a higher, flat-backed shape, so you get more headroom and more usable space inside, and the khaki VenTec fabric now has a 20,000mm hydrostatic head with a blackout laminate lining.
It also comes properly kitted out, with a zip-in groundsheet, a Vapour Peak and a Heavy Duty Storm Pole all in the box. At 18kg it isn't light, but for anglers who fish longer sessions and want a bivvy that's quick to pitch and built for proper weather, I think it's one of the best all-round choices out there.

How well is it built?
Fox have built the Frontier II around a lightweight aluminium frame, and the high, flat-backed design isn't just about looks, because it pushes the back wall up and out so more of the floor space is actually usable.
The khaki VenTec fabric feels like a proper long-session material, and the blackout laminate lining means you're not woken at first light by the sun coming through the canvas.
The joints are where you see the quality. The elbows are sprung-loaded and keyed, and the ergonomic grips give you something solid to hold when you're pushing the frame out, which makes a real difference with cold or wet hands.
It's the same attention to detail I liked on the Frontier XD, right down to the double-zipped carry bag with storm cord eyelets and a separate peg bag, and the whole thing feels like it's been designed by people who actually live in their bivvies for days at a time.
Stability & Weather Resistance
That 20,000mm hydrostatic head is a serious figure for a bivvy, and Fox include a Heavy Duty Storm Pole and the Vapour Peak, so you've got the extra support and the condensation control for bad weather straight out of the bag rather than as extras you have to buy later.
Ventilation is well thought out too. There are four all-weather vents covered with camo mozzy mesh, and you can open them from inside, which means no getting out in the rain to sort the airflow.
They also have pegging points, so you can keep air moving through the bivvy even when it's chucking it down, and that goes a long way to stopping condensation building up on a wet night.
The front is just as flexible, with a solid infill and three door panels in solid, clear and camo mozzy mesh, so you can shut it up tight in a storm or open it right up on a muggy summer night.
Ease Of Setup & Portability
The geared ETS BOSS system is the big help when you're pitching on your own. It takes the strain as you tension the frame and helps stop it collapsing while you're putting it up, and the refined release trigger makes taking it down easier as well.
Add in the sprung-loaded keyed elbows with their ergonomic grips and it's a quick bivvy to get up once you've done it a couple of times.
Inside, the widened front door makes getting in and out with kit easier, and the zip-in groundsheet has its own entry flap. There are four internal mesh pockets, a central hook and two door hooks, so the bits you need through the night all have a home.
Portability is the trade-off. It weighs 18kg, or 19kg packed, and folds down to 145cm long, so it's a bivvy for the barrow and the boot rather than a long walk with everything on your back.
Is it good value for money?
The Frontier II isn't cheap, but you're getting a lot for the money. The groundsheet, Vapour Peak and Heavy Duty Storm Pole are all included, and on plenty of bivvies those are extras that add a good chunk to the final price.
Compared with the Frontier XD, it's a newer design that costs a little less, and next to premium shelters like the Trakker Tempest RS 150 it's a good deal cheaper while still giving you a 20,000mm fabric, a blackout lining and a proper storm setup.
It comes in Green or Camo too, with bigger X and XL versions if you need more room.
It suits carp anglers who fish longer sessions and overnighters, want plenty of headroom and a bivvy that copes with proper weather, and are happy to barrow it to the swim rather than carry it any distance.
