A lightweight suit with a protective quilted Nomex® liner

The X30 Industrial Proximity Suit is a lightly insulated proximity suit that provides an impressive balance of protection and comfort. The X30 features a Z-Flex® aluminized shell for protection from radiant heat and a quilted Nomex® thermal barrier for protection from conductive and convective heat.

The Z-Flex outer shell reflects 95% of radiant heat and withstands radiant temperatures up to 3000°F (1650°C). In addition to providing outstanding protection, Z-Flex is also the most durable aluminized material available and will not de-laminate under even the most demanding conditions.

This suit can be used in a wide range of industries and applications including aerospace, heat processing facilities, foundries and petrochemical plants.
