DL87 armor enhancement

The DL-87 armor enhancement, also known as the "frostback", was a model of heating system available during the Galactic Civil War between the Alliance to Restore the Republic and the Galactic Empire following the Battle of Yavin. Built by Atlas Corp it sold for undefined1000 and kept its wearer protected from low temperatures using insulation and heating elements. It could be installed into any suit of armor that covered the entire body and was sealable.
