Most of that weight is saved via the use of a 10,000mm hydrostatic head material. You will find this material more than enough to get you through the colder months. However, expect some condensation drip throughout winter. At first glance, you’ll notice just how large the R-Series is. It’s a full 20cm wider than the Aqua Fast and Light. As a result, you’ve got sizeable footprint inside to fit days worth of kit. A term often bandied about when it comes to shelters, the hydrostatic head rating of a bivvy relates to waterproofing.

However, AVID have designed a brolly here that really can be used throughout the depths of winter, as well as the warmer months. The canopy of the shelter is constructed from PU-coated nylon, which has been treated to increase its durability and extend its lifespan. If you have decided that a brolly system is for you, here are some things you might want to look out for. Setup time

The main advantage of a brolly system over a traditional bivvy is the speed at which it can be set up. Fox’s offerings, from the fox bivvy 2 man to the single variants, stem from a lineage of passion for angling. When opting for a Fox product, you're tapping into decades of research, innovation, and first-hand angling experience. On the plus side, you do get an integrated front with the EOS Brolly. This is ideal for keeping the wind and rain at bay. Benefitting from a heaver hydrostatic head and larger footprint than the EOS, it provides that extra of coverage and comfort for those who want to use a brolly system all year.

The extended side skirts allow for extra protection from the elements in particularly bad conditions. The right bivvy can significantly enhance your angling experience, providing comfort, protection, and convenience. Fox International's bivvy range, from the Fox pop up bivvy to the R Series, caters to a broad spectrum of angler needs. The next time you're gearing up for a fishing expedition, understanding the features of these bivvies might just be the key to a more enjoyable outing.

What you get here is a very flexible brolly system, one that can get you through all but the harshest months of the year. They also add that extra little bit of space that could be handy for something like a bivvy table or a bivvy heater if the conditions are cold.

You’ve got a heavy duty ground sheet as standard and front/rear mozzie mesh to keep air flowing in the summer months. And secondly, the ribs are cut down to just 55 inches. With most brolly systems having 60inch ribs, this might sound like you’re losing some space. But with the extra rib and two redesigned ‘wings’, you’ve got more of a round profile that adequately protects you and your gear. The Fox R Series Brolly System features a space saving mechanism for increased internal headroom and comes supplied with zip-on, fully removable Fox R-Series Brolly Infill Panel that features three door options - clear PVC, solid Khaki and mozzy mesh.

The Fox R Series Brolly features a full-length zip on the front to allow an optional R-Series Infill Panel, Extension or Mozzy panel (all available separately) to be added at a later date. A fully blown shelter conversion featuring an attachable zipped infill panel that includes interchangeable mozzy, solid and clear PVC door options as well as two extra storm poles for stability. Retains all the fantastic features of the standard model, such as extra head space and a sturdy four-rib frame for extra rigidity. A 10,000mm hydrostatic head ensures a completely weatherproof experience, with this high-quality brolly set up keeping you sheltered, shielded, and dry through lashing rain and howling winds, making it a suitable alternative to a bivvy for anglers who want to fish without fuss. The R-Series Brolly System is supplied with two 24” front and two 26” rear storm poles, which come with threaded storm caps for a completely stable, durable, and reliable set up at any time of year, in any weather, and on any venue. A zip on/zip off R-Series infill panel turns this open front brolly into a fully enclosed shelter at the swish of a zip, and comes in a choice of solid PVC, which matches the khaki brolly, clear PVC, which allows you to keep an eye on what the water’s doing, and mozzy mesh, which is ideal for those balmy, pest-plagued summer nights. A two way zip creates a letter box doorway, that gives you the option of fishing from inside the brolly – often a sensible choice if the weather suddenly turns, and the rain that’s arrived doesn’t look like it plans to go anywhere anytime soon! You can buy a brolly extension that zips on to the front. It’s similar to an open awning, giving you lots of extra room for socials, cooking, or just storing kit on longer sessions. One of the key features (other than price) that sets this day shelter apart from the competition is its weight.

The figure relates to the height of a column of water that can be placed on the fabric before it leaks – so a 10,000mm hydrostatic head is better than a 5,000mm one. The Fox R Series 2 Man Bivvystands out with its 10,000mm hydrostatic head rating and spacious XL design, offering enhanced headroom and space. Built with a sturdy four-rib structure and 19mm aluminium frame, it features versatile door options and expansive mozzy mesh panels for ventilation. Weighing 21.5kg, it includes a heavy-duty groundsheet and pegs. For any dedicated angler, the quest for the perfect catch isn't just about the reel and bait; it's also about ensuring you're well-prepared with the right shelter. Fox International's bivvy selection encapsulates this belief, providing every fisherman – be it novice or pro – a sanctuary by the waterside. Why Choose a Fox Bivvy?Firstly, Aqua have added a 9th rib to the brolly, providing a peak in the centre. What this does is heighten your field of view, allowing you to sit up on the bedchair and gain a panoramic view of the water. There are 4 ribs that make up the frame of this brolly system which makes it sturdy and rigid and there is an option that allows you to change the doors from clear PVC, a solid Khaki door, or just the mozzy mesh. You will notice that it has a unique difference to the front though. This brolly features a peak at the front which helps to keep driving rain out when you’ve got the door set up letter box style. This is a nice addition that many brolly systems miss. Bear in mind that other factors, including taped seams and the fabric’s coating, also come into play with waterproofing.
