These hi-vis winter trousers are built for outdoor work in cold, wet and low-light conditions. A waterproof shell with taped seams keeps rain out, while the quilted lining holds in body heat during long spells outside.
Fluorescent fabric and retro-reflective tape help you stay visible to others. Practical details make them easy to live with, including side zip leg openings, pass-through pockets and a fully elasticated waistband. The fabric is also UPF 40+ rated for protection on bright days.
