Thermal Workwear and Base Layers

The Stormtech AFH1 Boulder Thermal Shell combines an insulated quilted body with stretch fleece sections. Its main outer and lining use nylon, while the secondary fleece fabric blends polyester with elastane. This construction offers a jacket option for staff who prefer a padded torso with a different fabric around the sleeves and side panels. The front fastening has an internal storm flap and chin guard, and two zipped hand pockets keep small essentials separate from your trouser pockets. An adjustable drawcord finishes the hem. The outer has a water-repellent treatment, but choose dedicated waterproof rainwear for sustained wet weather. Select your size and colour from Astral’s options, allowing room for your usual work layers.

The Portwest B120 Thermal T-Shirt is a short-sleeved base layer with a round neckline and comfort fit. Its 200gsm fabric combines equal proportions of polyester and cotton.

Choose the size and colour options shown for this product, and compare garment measurements with your existing layers before ordering.

Select a size that sits comfortably under your outer trousers without restricting movement at the waist or knees. The page offers several colours and sizes from XS to 4XL. Match the whole clothing system to the temperature and activity, and follow the garment label for washing and drying.

Contrast stitching provides a visible detail across the panels. This page lists Charcoal in sizes XS to 3XL. Choose a size that fits comfortably at the waist and knees without bunching beneath your outer clothing. The leggings provide an additional layer for cooler duties and changing activity levels, but the complete clothing system must suit the temperature, exposure and task.

A drawcord lets you adjust the hem around your clothing underneath. Choose Black or Dark Navy from Astral’s listed sizes and check the fit with your usual layers. Its water-repellent finish does not make it a substitute for waterproof rainwear.
