Don't assume the futuristic looks of this X-Bionic Extra Warm Shirt means it's designed to keep astronauts warm as they float from one section of the space station to another. This technically-advanced long-sleeve top is definitely for cold-temps and high elevation activities, but outer space may be a bit high. Key ventilation regions transfer moisture to permit evaporation while other regions retain warmth to dish out the most performance and comfort possible.
