Everest overalls have a design that has been thought-out to provide wearers with comfort while limiting the bellows effect (expulsion of particles and bacteria from openings).

All the designs of our overalls are tested in our Body Box to ensure their effectiveness.

After having undergone our decontamination process and, where appropriate, a sterilisation, they can be used in clean rooms and sterile environments with ISO 4 to ISO 8 or A to D classification.

They are available with or without hood.

98% polyester and 2% continuous-filament carbon thread fabric. It filters contaminants of human origin, while still allowing ventilation and remaining comfortable.
Hood able to isolate the wearer's head.
Zip fastener offset to the left allowing limitation of the bellows effect
Rib trimmings to limit the bellows effect

Many tests are carried out to check that the properties of the fabric are maintained during the different treatments that will be carried out.
 
Some characteristics of the fabric between 1 and 60 cycles of particle decontamination, with or without sterilisation (qualification report data):
  • fabric's excellent ventilation capability ensures comfort for the wearer
  • 98% of particles emitted by the wearer are contained
  • fewer than 2,000 particles of diameters ≥ 0.3µm emitted by overalls when working (Body Box test)
  • fewer than 310 particles of diameter ≥ 0.3µm emitted by overalls in Helmke drum
  • no penetration of bacterial contamination through the fabric
  • fabric's dissipation properties.

The Ultra Clean service

Work within a clean room requires the use of special clothing and appropriate maintenance.

Our maintenance consists in undertaking:

  • a particle decontamination treatment (category 1 or 2) in accordance with IEST RP CC003.3
  • autoclave curing sterilisation or radio sterilisation
  • particle inspection in Helmke drum for each batch
  • traceability of each garment via chip or bar code.

The clothing we offer via rental/maintenance service can be used in clean rooms and sterile environments with ISO 4 to 8 or A to D classification.

This service is ISO 9001-certified.
