Tyvek Dual Coveralls have been designed for specific applications where demanding comfort requirements are combined with limited protective requirements for frontal exposures. They are well suited for workers who are involved in strenuous activities that can lead to heat stress in applications that include: manufacturing, utilities, remediation and maintenance. These garments offer the protection, durability and comfort of Tyvek® fabric on the front with the increased breathability of ProShield® fabric on the back. The result is a garment that provides excellent durability, an inherent barrier to fine particles on the front, and increased breathability for reduced heat stress and enhanced comfort on the back. Tyvek fabric on the front is composed of flashspun high-density polyethylene. ProShield fabric on the back is made from a polypropylene SMS (spunbond meltblown spunbond) and is optimized for comfort, softness and breathability.
