Maybe a modified version of the diving suit that has a built in back pack system equivalent to the medic jumpsuit

Or a backpack that is built purposely to be used with the diving suit that has a 60% movement speed penalty that is reduced to 10% when the diving suit is equipped

I'm not entirely sure something like that would be possible, would be difficult to make the backpack change params while wearing a specific item, unfortunately the game isnt coded in such a way. I found a way for an item to require another item to work but not to add or change additional params. however the diving suit idea isnt too shabby, ill see what I can do

i came looking to relieve myself of the pain unloading items into the ship brings, but the bleeding and armor perks your stuff provides makes me feel like i'm cheating instead of just alleviating a design pain point.
