I have a really hard time getting my drysuit zipped on and off. Mostly just the part thats up over the top of my shoulder. Does anyone have a trick they know for getting this accomplished without having help from a partner?
Waxing the zipper helps a lot. I've found that on my Kokatat GMER suit that I can put my left hand thumb into the end of the zipper cover (near my right shoulder) and pull with my right hand (a few tugs) and the zipper moves enough to grab and finish the zip with my left hand.
I've also found that it's much easier to get into the suit with my right arm first and then follow with the left arm. Reverse the process when taking off the suit (ymmv but it works for me).
