These insulated walking trousers are a cold-weather essential. Pairing a splashproof outer face with a fleecy, quick-drying lining, they offer extra warmth in cooler conditions. Made from tough sun-protective and insect-bite-proof fabric, they're a smart choice for the outdoor trail on icy mornings. The trousers feature H2O Shield PFAS compliant durable water repellent finish, Solar Shield fabric for UPF 30-50+ protection from UV rays, and specially constructed fibres that are too tough for insects like mosquitoes to penetrate. They also have reinforced double layer fabric to the seat and knees, and a scrim lining or brushed back for added warmth.
