You can flood your suit to stay cooler when you're in the water, or pour some water down your suit before getting into the water as spectrum said. The Hyperstretch is so easy to get in and out of, it won't take you long at all.
There are other vests with zippers, it just depends on how thick and how flexible you want it. The Hyperstretch is so flexible, you don't need a zipper. The Henderson Gold zippered vest dries fast and is easy to get on and off, NeoSport also has a zippered vest that's easy to get on/off. The zipper will also decrease the effectiveness of keeping cold water out when you're doing colder water dives, than a vest without an opening like that.
Hope you find what you're looking for in the right combination!
