How does the rear zip let less water in the boat? Don't they both meet the skirt at the tunnel? My GMER stays completely dry.
The zipper across the front creates a little gap with my skirt when i bend around, the Icon lets the skirt sit better. It's really not that big of a deal and may be entirely in my head. I normally paddle dagger boats so there's always a ton of water in my boat regardless.
The bigger issue is the range of motion and comfort issue. The zipper across the back just gets in the way less than the zipper across the front.
