Inside the space station we have a comfortable environment. We have air at the same pressure as on Earth, and the temperature is about 22°C. To work, we usually wear T-shirts and trousers with plenty of pockets and a lot of Velcro stripes to attach things. We only wear socks – no need for shoes!
I have one pair of trousers per month, one T-shirt per week, and I can change underwear every 2 days and socks every four days. I also have separate sets of exercise clothes. I can choose between which of my clothes to wear, for example whether I wear long-sleeved or short-sleeved shirts.
There are some materials we don’t wear often in space, due to their properties. We typically don’t wear synthetic fabric, except for exercise, because it is flammable. We mostly wear cotton!
