Guy Cotten Isomax Waterproof Jacket

The Guy Cotten Isomax Jacket is a high‑performance professional waterproof jacket engineered for demanding marine and industrial environments. Designed as a longer version at the back for improved protection when bending, it combines innovative technology with exceptional durability.

The Isomax features two major patented innovations: the Isolatech technique, which reduces condensation by insulating key contact areas (shoulders, chest, and upper back), and the “MAGIC” hood, which moves with the head to maintain clear visibility and allow the wearing of a hard hat.

With a kimono‑style cut for enhanced freedom of movement and reinforced fabrics in high‑wear zones, the Isomax delivers superior waterproof protection and long‑lasting comfort. For maximum protection, it can be worn with PPE‑classed trousers or bib & braces.
