Put the zipper to the front side. You could wear it alone without asking for help from another astronaut and save time in case of emergencies.

You think the issue of where to put the zipper didn't come up in the thousands of man-hours it took to design that thing?

  Design by committee? In which case the zipper is definitely in the least practical place. Anyway, it's an interesting question that possibly has some story to it which would be interesting to hear.

    > In which case the zipper is definitely in the least practical place. Argh! How would we even know it's in the least practical place? Is it because you don't put on your coat that way? These things are not designed with the same constraints. Getting into a space suit is a slow deliberate process, with people there to help.

      I can think of at least one edge case where things might be different. Emergency re-entry, time to put on your suit, but everyone else is dead. But anyway, I'm just saying it would be interesting to know why certain design decisions were made, what trade-offs were considered, requirement constraints. Saying something like you reckon they didn't think of that doesn't add to the conversation.

  Sure they thought about... anyone knows the reason for that? I see 1 case in which it would be fast to dress up (emergency reentry, as TheSpiceLife said ..see [0]) and 2 to take it as fast as possible (toilet emergency and support system failure).. Well, with all respect, a 1000 people thinking about a single point doesnt mean much.. we unfortunately saw catastrophic events caused by apparent single failures..

Easy: add a string to the zipper, like for scuba diver suits.
