I have Zero Restriction as well, and I actually bought it used (BIG RISK), but was happy to find out that the were brand new. My Zero Restriction pants do have zippers to convert to shorts. The guy I bought from couldn’t have worn the suit more than once, if that. I also bring two or three sets of rain gloves, and I use Gorilla Grip to put on my grips and golf gloves…not only for rain but for heavy humidity as well.
Three years ago, I made it to the finals when there was a hurricane coming through. In our group, I was the only person that didn’t hit my tee shot into the weeds on the first hole. Love the Gorilla Grip for rain and humidity.
