Newtex X10 Ultra-Lite Proximity Suit

Newtex X10 Ultra-Lite Proximity Suit

Manufacturer: Newtex

Product Code: X10


The X10 Ultra-Lite Proximity Suit is an extremely lightweight and flexible suit intended for industrial applications. The X10 is fabricated without bulk insulation or lining for superior flexibility and freedom of movement. It is available with the option of three different types of Z-Flex® Multilayer Aluminized outer shells, each material features unique strengths.

Z-Flex 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 foundries, processing facilities, and other environments where workers are exposed to radiant heat.

Ensemble Features


  •  Narrow collar
  •  Set-in sleeves
  •  Snap adjustments on sleeve cuffs


  •   Sewn-in elastic suspenders for adjustable pant drop

Hood, Boots, and Gloves

  • The X10 ensemble includes a jacket and pants only, however, the X20 hood, boot covers, and gloves can be purchased with the X10 ensemble for an additional cost.

Suit Construction

Radiant Shell Options:

  • Z-Flex® K-252 Aluminized Para-Aramid for added abrasion & puncture resistance
  •  Z-Flex® R-480 Aluminized FR Rayon for increased flexibility and comfort
  •  Z-Flex® O-500 Aluminized O-PAN / Aramid for superior insulation

Suit Weight

 Nominal weight: 4 lbs (1.8 kg)

  •  The nominal suit weight is the total approximate weight of the jacket and pants. Actual weights may vary slightly.

The X Series suits incorporate the latest apparel design features to provide outstanding flexibility, dexterity, and comfort while maximizing safety and efficiency. With more than a dozen options, we are certain that you will find an X Series suit that meets your requirements.

When selecting a proximity or fire entry suit, it is important to consider the convective, conductive, and radiant heat risks in your work area and the length of exposure to that heat. The advanced aluminized outer shell of the X Series suits provides the ultimate protection from radiant energy, the heat transmitted from all hot objects. The X Series also provides protection from conductive and convective heat. The level of conductive and convective protection increases with each suit as you move from the most lightweight suit to the heaviest.

The radiant performance graph above illustrates the radiant protection provided by each of the three X10 radiant shells and the leading competitive aluminized shell. The graph illustrates the temperature of the cold-side of the aluminized shell as it is exposed to radiant heat of 2.0 cal/cm2 sec over a two minute period. The test results show the temperature of the X Series shells increase slowly and steadily compared to the leading competitive shell which fails catastrophically. The heat source used for this test is extreme and not necessarily representative of all real world scenarios. The test is intended to show relative radiant protective values of the aluminized shells in relation to each other. Real world industrial maintenance and emergency response environments are likely to be unpredictable and vary from test conditions. We recommend only professionally trained industrial workers and emergency personnel use these suits under established safety protocols.
