After you have mastered the art of day fishing, you'll soon want to be out on the bank at night too as you never know when those carp are going to start biting. With this in mind you'll be needing a some kind of shelter - generally a bivvy. These range in size and how easy they are to put up with more and more coming with super quick easy set ups. Some people even like to make sure they're sheltered from the rain in the day time too so a day shelter or large umbrella might be the best course of action for you. Some bivvies let less moisture in than others so it might be advisable to make sure you have an overwrap to make your overnight stay at the bank more enjoyable.
