My Evertech utilizes the O-Rust system. I don't use drygloves as I am a harvester / hunter and just prefer to use 5mm gloves. Pectin scallops are like little razors and will breach a dryglove quickly. I also like the option of removing my gloves if interacting with wolf eels or octos. I keep an extra set of wrist and neck seals in my save-a-dive kit and can change out in about 5 minutes if needed. Have not needed yet.
