Focus on the fill material. Down alternatives like polyester and lyocell are more breathable than down. Check the shell fabric; cotton and lyocell are best for airflow. Look for a lightweight or medium weight insert. Avoid heavy down fills that trap heat.
Down is warm but can overheat. Down alternatives are synthetic and often cooler. Lyocell is a plant-based fiber that wicks moisture. Outlast technology absorbs and releases heat. Choose based on your sleeping temperature and preferences.
Cotton is a classic choice, but percale weaves are more breathable than sateen. Lyocell is silky and highly breathable. Some shells have a cooling finish. Look for a shell that is soft and allows air to circulate.
