This, there are Pioneer bits you can put on your suits including a few helmets. BUT the issue w that entire process is while those bits “may” be on y suit you have to install them twice to show in the corresponding boxes on the left. This applies to suit customizations…
i found its not so much 'install twice' (sort of) but that original UI panel only updates itself after you move out of it and back again,
example:
you update your outfit torso, select the box and then the various parts show (sort of, seems to always show the arm icons for me, but whatever), select the pack and color
once back in the main outfit management, the torso box is still empty, but select the arm slot, choose the pack/color
back in the outfit management, NOW the torso slot has updated, but the arm slot still shows as empty.
Its a state management issue that's all over the UI (eg. ship repair/maintenance and refueling) in alpha. Assuming its still the same.
