i can highly recommend the cyprinus gear, i have had the bivvy's myself and always found them to be well put together, not the lightest of gear but great for someone starting out.
i also have the cyprinus wide guy bed chair (cos i love to spread out) and the 5 season sleep system bag is (imo) one of the best on the market.
bivvy or brolly system is the oft asked question and the proper answer is 'look at your intended fishing style' if your going to be doing mostly social type fishing, I,E, couple of mates on the bank for a 24 hr get together, Bivvy for comfort every time.
solo nights and wanting to be semi mobile then brolly system pref with overwrap for those cold ones coming up, this comes in handy when you want to move to get on the fish or you are faced with a mega hike to your spots.
an intermediate bivvy to cover both situations is the TFG force 8 bivvy
so easy to put up and down, literally seconds and a reasonable price too, i had one for 4/5 years and it was excellent, in fact i still have it in the shed
