Teyora Rekab is shown wearing a coolth suit. Coolth suits represented a type of protective gear crafted specifically for species adapted to frigid climates, such as the Ensos. These suits enabled survival on planets characterized by elevated temperatures, like Tatooine, the Bright Lands of Ryloth, or Cairns. To illustrate, Ensos, who were accustomed to the sub-zero conditions of Ensolica, had no choice but to don these unwieldy suits to prevent almost immediate heatstroke.
The design of the suit incorporated extensive networks of tubing, stretching across numerous meters. This tubing formed a complex pattern, routing from cooling mechanisms, encompassing the body, and then returning. The suit's extremities were layered with a reflective substance, which served to minimize the absorption of excessive solar radiation. Positioned beneath the chin were a pair of air intakes, which facilitated the entry of high-temperature air into a circulatory system. This air was then directed into the helmet's transparent dome before being discharged through exhaust ports situated at the top. Typical coolth suits lacked supplementary air purification features, such as filters for dust or chemical scrubbers. The helmet's dome did not feature a polarizing filter to protect the user from intense sunlight, which resulted in some individuals wearing polarized goggles beneath it.
The temperature settings of coolth suits could be adjusted, but more economical versions frequently had fixed settings to minimize the rate of mechanical breakdown. This occasionally resulted in wearers needing to put on thick insulating clothing underneath their coolth suits to ward off hypothermia.
Coolth backpacks served as a more lightweight option for some, notably for inhabitants of Mos Espa.
