Rain gear
From KayakWiki
Rain gear - there's a topic to get campers wound up.
Some folks just go with the paddling gear they wear. After all, if it's good enough to get wet paddling, then it's ok at the campsite. However, that isn't the most comfortable option especially in cooler seasons. Others are firm believers in good GoreTex or other waterproof breathable outerwear. Then there are those who claim that the former doesn't work, is too expensive etc and go with cheap plastic, nylon or heavier PVC rainwear.
GoreTex type fabrics do work and provide for considerable comfort. The other fabrics will remain waterproof for quite some time, but tend to have condensation problems - insensible perspiration condenses on the inside of the garment and makes you feel damp. The cheap plastic gear tends to tear easily and the heavy PVC stuff is a bit bulky for packing into a kayak. Nylon seems a good compromise. Most non-breathable fabrics, especially the lower cost ones, tend to break down and lose waterproofness over time.
Instead of jacket and pants, some prefer a poncho. Ponchos provide good coverage and, being loose fitting, tend to have less condensation. They can be used as a tarp or wind/sun screen in a pinch as well. The downside is that they tend to blow around. A belt around the middle isn't much of a fashion statement, but does help control the poncho.
Don't forget your head. Either a hood or a waterproof hat is a essential. Kokatat makes a decent sou'wester (called Sea Wester) that looks better than any other I've seen in a while - waterproof breathable in bright mango with a black brim underside to keep glare out of your eyes. The brim is foam filled so it floats.
A baseball cap under a hood provides a brim to keep rain off of glasses.
