Synthetic fabrics like polyester, nylon, or rayon may be affordable and lightweight, but they aren’t ideal for air travel. These materials don’t breathe well and can trap moisture, leading to overheating or feeling sticky, especially in the confined space of an airplane cabin. In the event of a temperature change, synthetics can make it harder to regulate your body heat, leaving you either too cold or too hot.
Instead, choose breathable, natural fabrics like cotton, wool, or bamboo blends. These fabrics help regulate body temperature better and wick away moisture, which keeps you comfortable in fluctuating temperatures.
