Trellchem® EVO comes in three different designs to fit all user preferences:

  • Encapsulating design type CV
  • Encapsulating design type VP1 (larger visor)
  • Non-encapsulating design type T


The combination of elastomers and plastics with a Nomex® fabric makes a strong and flexible material that offers an outstanding chemical barrier - more than 24 hours protec­tion against a wide range of chemicals including warfare agents - coupled with an excellent resistance to attack from aggressive chemicals (provided by the outer Viton® layer) and flame resistance. The material has impressive abrasion resistance, withstands flash fire & liquefied gas, is antistatic and fulfils all garment material requirements of the most demanding standards in the world. U.S. Patent.


The seams are stitched with aramid thread for superior strength and durability. On the outside the seam is sealed with a glued-on rubber tape and on the inside with a welded-on barrier laminate tape. The welded-on barrier tape provides a continuous barrier layer across the seam, giving the same chemical protection as the garment material itself.
