Embodiments of the invention relate to a cover, a method of covering, and a cover system to be used with shipments of products transported by air with ULDs. The cover system provides thermal protection to temperature-sensitive products in or on the ULD. The cover system maintains the proper relative humidity level and gas concentrations (oxygen, carbon dioxide and ethylene) for horticultural product loads. The cover system can also have antimicrobial properties. In addition, the cover system decreases the amount of water vapor released in the cargo holds which is known to affect the reliability of the aircraft smoke detection system and to cause false fire alarms.
