Portwest DX4 Hi-Vis Winter Coverall DX438

Portwest DX4 Hi-Vis Winter Coverall

When winter weather demands serious protection on site, this hi-vis winter coverall delivers exactly what you need. Engineered from premium 100% polyester stretch fabric with a PU membrane, it combines thermal comfort with practical functionality. The 4-way mechanical stretch means you move freely without restriction, whilst the PFAS-free TexpelSplash Eco finish keeps water beading away from the surface. With heat-applied reflective striping meeting strict visibility standards, an adjustable hood, and strategically positioned knee pockets, this winter coverall handles everything from cold snaps to demanding outdoor work. The taped and sealed seams ensure water stays outside where it belongs, and the InsulatexPro lining provides genuine warmth without adding unnecessary bulk.

Key Features

• 100% polyester stretch with 4-way mechanical movement
• Sealed seams and waterproof zips throughout the garment
• EN 342 cold protection rated to minus 40 degrees
• Adjustable hood and reinforced storm flaps included
• Eight storage pockets plus knee protection positioning

Recommendations from our Unishore Expert

This coverall sits at the sweet spot between investment and performance. The stretch fabric means you're not fighting the garment when reaching, bending, or climbing, which translates to less fatigue over a full shift. The InsulatexPro insulation actually keeps you warm without that heavy, restrictive feel you get from traditional padded gear. Choose this when you're working through genuinely cold conditions and need visibility on site-the reflective striping does the job properly, and the hood adjusts both ways so it fits whatever you've got on underneath. The taped seams matter here, because water-logged clothing leads to rapid heat loss, and this keeps that from happening.
