Men’s Thermal Underwear and Base Layers for Cold Weather
A comfortable first layer makes colder days much easier to manage. Our men’s thermal underwear and base-layer collection brings together long johns, close-fitting Henleys and textured cotton thermals designed to add warmth without creating excessive bulk beneath your clothing.
Choosing the right base layer
Start by considering how and where you intend to wear it. Long johns provide additional coverage beneath jeans, chinos and work trousers, while long-sleeve Henleys layer naturally beneath shirts, sweatshirts, knitwear and jackets. Short-sleeve base layers offer lighter coverage when a full thermal top would feel excessive.
A base layer should sit reasonably close to the body so that it fits comfortably beneath other garments. It should feel secure without restricting movement or pulling tightly around the shoulders, waist or legs. Check each product’s individual size guide, as fits and fabric weights differ between brands.
Cotton rib and waffle thermals
This collection includes soft organic cotton rib jersey from Hemen Biarritz alongside diamond-patterned cotton thermals from Merz b. Schwanen and heritage-inspired Henleys from Pike Brothers.
Ribbed fabrics provide comfortable stretch and a streamlined fit, while waffle and textured thermal constructions create small pockets within the fabric that help retain warmth. Lighter jersey styles work well as everyday first layers, while more substantial waffle fabrics are particularly useful during colder weather.
Long johns for layering beneath trousers
Long johns are designed to provide full-length coverage without the weight of another pair of trousers. Wear them directly against the skin beneath denim, chinos or work trousers. A close fit helps prevent the fabric from gathering and makes them easier to wear throughout the day.
Heritage-inspired everyday layers
Many of these garments take inspiration from traditional underwear and early workwear base layers. Details such as buttoned Henley necklines, ribbed organic cotton and substantial waffle fabrics give them enough character to be worn on their own while retaining their original usefulness as practical first layers.
Follow the care instructions supplied with each product, particularly when washing organic cotton or heavier waffle fabrics. Avoid excessive heat where advised to help preserve the fit, shape and texture.
