Hey, Don't know if others have this problem, but Frabill I3's come with a zipper that does nothing due to an internal flap. To take a leak, you need to unbuckle. I took my set to the local Cleaners that also do alterations and had the flap cut and a zipper installed. Cost was only $26, cheap to me. I had contacted Frabill about this oversite and they said they did it for moisture protection. Moisture protection, I am standing on frozen water and slush and have to piss???
Ches.
