Recommendations from our Unishore Expert

For those working through winter conditions, these winter work pants offer reassuring protection. The removable front and rear panels mean you're not locked into one configuration, which works brilliantly when you need to adapt during your shift. The InsulatexPro lining keeps you warm whilst maintaining enough breathability to prevent overheating during physical work. Taped seams protect against water ingress, and the water-repellent fabric treatment means morning damp or unexpected spray won't soak through. The 16 pockets are genuinely useful rather than just marketing speak, especially the positioned knee pockets which work with optional knee protectors. The elastic waist and stretch fabric combine for comfort during long working days without compromising the smart appearance.
