Lightweight, affordable dry pants/top for packrafting?

I owned a previous version of these dry pants before switching to a drysuit. Being designed for kayaks, most dry tops (that have a seal to mate with pants like these) also have a double tunnel, which you don’t need for packrafting, making for extra weight. In my experience, a dry pant/top combo will work for splash, but you will get wet if you swim. Alpacka’s drysuits have a center zip, so you can use just the top or the bottom as does the Kokatat Surge, which I use (and am very happy with so far.) If you have a whitewater deck and are banking on not swimming, a dry top may make sense for some trips, but usually it’s the bottom half that comes in the most handy for me.
