This hi-vis winter coverall is built for outdoor work in cold, wet weather where you need to stay visible. It combines a waterproof, breathable stretch shell with padded insulation, so you stay warm and dry while you bend, reach and climb.
One-piece construction keeps your back and waist covered as you move. Plenty of storage and easy-access zips make it practical to wear through a full shift.
Key features
- Waterproof, breathable fabric with mechanical stretch moves with you and keeps rain out
- Taped seams and waterproof zips help keep water out, and seam-free shoulders add further protection
- Eco-conscious water-repellent finish makes water bead off the surface
- Insulatex™ Pro padded lining provides warmth without adding unnecessary weight
- Detachable hood with vertical and horizontal adjustment, plus a brushed micro fleece collar and chin guard with internal storm flap for comfort around the face and neck
- Storm flap over the two-way front zip shields the opening from wind and rain, and hook and loop cuffs close securely at the wrists
- Articulated sleeves and darts, a crotch gusset and side elastic waist ease movement; the gusset reduces stress on the seams and helps prevent seam failure
