Tyvek® Classic Plus Coveralls

DuPont™ Tyvek® Classic Plus Coveralls – the Best of Both Worlds

DuPont™ Tyvek® Classic Plus garments (model CHA5a) combine the performance of a Type 4 coverall with the durability, protection and comfort of a Tyvek® suit.

Tyvek® Classic Plus is made of Tyvek®, but the coveralls offer the added benefit of protective design features and over-taped seams. They help provide an effective barrier against many water-based inorganic chemicals in low concentration, small sized hazardous particles and biological hazards. These coveralls are ideal for occupations that require effective whole suit protection offered by a Type 4 suit because they are exposed to heavy liquid aerosols or toxic airborne solid particulates. Yet, being robust and breathable they help offer an ideal balance of chemical, particulate protection and comfort.

Recent update:  new packaging for an improved garment

Enhanced design for increased flexibility and comfort

  • Improved garment fit: extra flexibility and freedom of movement
  • New hood design: optimised to fit the contours of the face, ensuring fewer leakage points during head movement
  • Larger zipper puller: much easier to grasp when wearing gloves.
  • Certified to latest European Standards: including the Type 4 spray test, which is 3x more stringent than its predecessor

New packaging:  Informative and educational

New name and model references: to reflect the product changes
