Chub discovery 2 Man, ive had mine for 3 years now, all ive had to do is just apply some seam sealer after 2 years. Ask those I fish with, its plenty big enough for 2 people plus the amount of gear I take for 5 day stints is a little over the top (although very much needed) lol.
If they havent been updated you can pick one up for about 80.
Iv'e recently bought the Trakker Armadillo mk2 2 man bivvy . Its huge inside &very easy to erect ,A bit heavy but that goes with the Quality&workmanship &the pram hood style Cost around 350.00 .Also you have a PM.
Your mates not shown it, but I have a Fox Easy Dome.
Cost's about 175 sheets, really quick and easy to put up (literally 2 minutes included pegging) which is important especially for the winter as sometimes I might turn up during the darkness and in bad weather so I can't really be doing with pole threading.
It is a 1-man version which I prefer as you can get them into tight swims, but still has plenty of space to store your bits and pieces and also you will retain heat a lot better in a smaller shelter than you will a bigger one.
It is a twin-skin construction which aids in preventing condensation.
Did it rain or what Muskie! I tried my new bivvy out at the Northern, a TFG Force 1 man. Loads of room, completely watertight and like the other bivvy mentioned above it has in-built poles, goes up in seconds.
