Thermal Work Trousers

When the temperature drops, you need gear that keeps the cold out and the warmth in. Our range of thermal work trousers at AlexDirect is designed for professionals who work in challenging conditions — from frosty mornings on-site to draughty warehouses. Whether you’re after insulated trousers, fleece-lined options, or thermal base layers, we’ve got everything you need to stay warm, comfortable, and focused on the job.

Thermal Lined Site Trousers:

Our thermal lined site trousers are built for cold-weather performance on demanding job sites. With insulation that traps heat and outer materials designed to take a beating, these trousers offer reliable winter protection without restricting your movement. Ideal for trades working outdoors in harsh winter conditions.

Fleece Lined Work Trousers:

Tackle tough shifts in the cold with our fleece lined work trousers. Combining warmth and durability, these trousers keep you insulated while maintaining flexibility. Perfect for loading bays, early starts, or outdoor labour — fleece-lined workwear helps you stay focused when the chill sets in.

Thermal Long Johns for Work:

Add an essential layer with our thermal long johns for work. The Regatta Long Johns offer a comfortable, close fit that traps heat and wicks away moisture, making them ideal for layering under trousers in winter. For premium performance and active warmth, the Helly Hansen Lifa Pant delivers lightweight insulation and superior breathability — perfect for high-intensity site work.

Base Layer Thermals for Work:

Our base layer thermals for work provide that crucial first layer of warmth during winter shifts. Pair your long johns with the Regatta Short Sleeve Thermal Top — a lightweight, thermal layer that keeps your core warm while allowing full freedom of movement under heavier outerwear.
