Another subsidiary of Sioen, Mullion aims to protect in nature’s harshest, most unforgiving environments. Our garments are tailored to withstand sub-zero temperatures to prevent the onset of cold shock and hypothermia. Many of our suits have an inherent buoyancy to keep our wearer safe in deep bodies of water. However, it is important to remember the quality of these garments is such that they are legally required to be checked over annually to check for any wear.
