Never saw a need for a hoodie - but then, I'm probably too old to relate to you young punks that think they are cool...
I do wear my long sleeve sun shirt, over which I wear a light polartec top, and over that for paddling out and back through the surf zone a waterproof paddling jacket. I'll remove and add layers as the weather dictates, but most of the time I'm down to the sun shirt from mid morning to sunset.
For bottom wear a pair of trekking pants over which I'll wear a pair of Kokatat dry pants. If it gets warm, which it usually does in the afternoon the dry pants come off.
Luckily I drive a PA to support all this changing activity...
