ChemMax® 3 Cool Suit coverall with elasticated hood, cuffs, waist and ankles

Style Number: CT3SCF428Translations

The Cool Suit^® principle uses the main chemical protective coverall fabric for the garment and includes a breathable back covered by a flap sealed at top and sides. The innovative design allows circulation of air into the suit - enhanced by wearer movement - to radically improve comfort yet maintain protection against Type 4 liquid sprays.

ChemMax 3 grey fabric with orange seams and rear panel cover for easy identification.
Coverall with elasticated hood, cuffs, waist and ankles and breathable rear panel.
ChemMax 3 fabric works with PermaSURE^® - on-line tool for easy calculation of safe use times against over 4000 chemicals.
Improved Super-B style coverall: superior fit, wearability and durability.

Features: Tape sealed seams, Breathable back panel, Double zip / storm flap front fastening, Elasticated hood, waist, cuffs and ankles, "Super B“ pattern

NOTE: Permeation test data relates to "Normalised Breakthrough" which measures the time for the permeation rate to reach a specific speed (In CE EN 6529 testing, 1.0µg/min/cm2 and in US ASTM F739 testing, 0.1µg/min/cm2). This does not indicate when the chemical first breaks through the fabric and is not an indication of how long the suit can be safely used as the chemical may have permeated through the fabric before the Normalised Breakthrough time. This might be critical in cases of chemicals with high toxicity.
