The cheapest Nomad Suit is the hazmat already in your box. The repair bench can apply skins you own to items you hold, so a plain suit takes the wanderer's look without a second set of tarps and kits going into it. With tarps as scarce as they are, that is a whole suit saved.
A fresh one is no separate craft. There is no Nomad blueprint and no research: you craft from the hazmat suit recipe at a Level 2 workbench and pick the look if it is yours. The game text promises nothing against heat or sand, so the choice is looks alone. Craft a new one only for a teammate who has no suit yet.
