Immersion Research makes a nice one. definitely the most comfortable option since you don't have several layers across your stomach, but there are some downsides: when the top wears out, the skirt is useless (skirts generally last longer), and it's great for surf or playboating, but i don't like the idea of creeking or river-running with it. if you get pinned with something across the cockpit, you can't swim out of the skirt tunnel.
