ChemMax™​ 1 Cool Suit with elasticated hood, cuffs, waist and ankles

Style Number: CT1SCF428

ChemMax™ 1 version of the Cool Suit. 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.

  • Yellow ChemMax 1 fabric with green seams and rear panel cover; easy identification.
  • Critical areas - hood, front torso, sleeves & legs are ChemMax 1 chemical barrier fabric; covered breathable panel to rear sealed at top and sides and open at the bottom to allow air circulation.
  • Stitched & taped seams
  • Improved Super-B style coverall: superior fit, wearability and durability.

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

Physical properties data is based on standard tests required by CE certification designed to allow easy comparison of the strength, durability and robustness of different garments. Lakeland's "Guide to Chemical Suit Selection" contains easy reference comparison tables of Lakeland garments with main competitors along with a glossary with brief explanation of the tests.

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.
