Basic Environmental Protection for a Plated Vesk?
Title. Ran into this issue in a SF Society session earlier, where my husband's PC is a plated vesk. Per the heritage description, they count as exposed, and can't equip armor upgrades in it (from what I can tell, the usual way to get basic environmental protections.)
---Your scales count as medium armor in the plate armor group. They grant a +3 item bonus to AC, have a Dex cap of +1, a check penalty of –2, and a Strength threshold of +3, and have the comfort and exposed traits. This item bonus increases to +4 at 5th level. You can wear a flight suit, but you can't wear other armor. You can etch armor runes onto your scales, but you can't install armor upgrades.
The commercial flight suit has no upgrade slots (I'm aware the tactical one has a single upgrade slot, but we're level one), and he can't wear other armor. What are the options for him to get basic environmental protections before level five? Or is this just an insane oversight? (Most of the table have only played like, two sessions of sf2e so it's entirely possible that all of us are just missing something obvious.)
