Space clothing is integral to the life of a spacer -- be they a temporary crew member on a spaceship, or a veteran navigator. Though spacers (and astronauts, spationauts, or however spaceship crew are called in their local culture) do not form a coherent cultural group and as such do not have anything resembling "traditional clothes", certain types of space clothing are found all across human space.

Casual wear for spacer is very often aerospace-inspired, with countless declination of the industrial-era pilot jacket, which might be modified and interpreted to such an extent that it becomes unrecognisable for whoever is not familiar with the history of human spaceflight. Indeed, and contrary to what a certain brand of science fiction may have predicted, spaceships, be they military or civilian, aren't based on boats, and spacers don't consider themselves as the heirs of the sailors of old. A common saying among them is that "space is a deeper sky" -- a way to signify that, by and large, they see themselves as pilots first and foremost.

Flight suits are the most common space garments, and indeed the type of clothing most commonly associated with spacers. Very closely inspired by worksuits or jumpsuits -- which themselves became extremely common during the post-apocalyptic Low Age, due to their ease of production -- these single-piece garments can be worn as is, over underwear, or over casual clothes. They are an integral part of workplace safety, providing protection against cuts and bruises, thermal regulation (within reason), high-g compensation (by inflating pouches in the legs during high-g manoeuvres to keep blood from rushing away from the head), tactile interface with various on-board systems and, when worn with gloves and a flexible helmet, airtight insulation. Flight suits are worn with short sleeves aboard ships that are known for running hot -- often fast vessels with low heat dissipation capabilities. The ship's heraldry is embroidered on the chest. Spacers typically own a dozen flightsuits each.

Mechanical counterpressure suits are also a common sight, and worn in place or over flight suits on many vessels. These suits allow for hard vacuum exposure and extra-vehicular activity. Instead of being pressurised and inflated like a regular hardsuit (the stereotypical, large, bulky spacesuit that's still very common in popular vision of spaceflight), counterpressure suits use tight elastic garments to apply pressure on the skin exposed to hard vacuum, preventing decompression of the spacer's body. Cooling is ensured by evaporation inside the suit. A counterpressure suit allows for unconstrained movement and can be worn inside or outside a ship, without the need for removing or donning the garment in the airlock. The suit links with the user's monad, allowing for fine instinctive control of manoeuvring thrusters and electronics. Most counterpressure suits can be worn on the surface of temperate (but otherwise hostile) planets, albeit very hot or very cold atmospheres require additional heat regulation capabilities: such suits are slightly bulkier and known as exosuits.
