Our thermals collection is cleverly designed using insulating materials like Thermolactyl, delivering practicality without compromising on style. Our men’s thermals have five grades of protection, from soft warmth if you’re staying in the house to intense warmth, ideal for spending a long time outdoors.
We offer five unique warmth grades; each tailored to different needs. For example:
Thermal grade | Description | Season | Example |
Grade 2 | Everyday Warmth: Perfect for day-to-day wear during cooler weather. | Summer/autumn | Taking the grandkids or dog for a walk in the park |
Grade 3 | Provides added insulation for winter walks or outdoor activities. | Autumn/early winter | Strolling through a Christmas market with the grown up children |
Grade 4 | Designed for prolonged time outside in cold conditions. | Winter | Going to an outdoor bonfire with little wind cover for an evening |
Grade 5 | Maximum protection for very low temperatures or extended outdoor use. | Winter | Hiking outside for more than 3 hours in below 0 temperatures |
Choosing the right men's thermals depends on how and where you'll be wearing them.
Thermals should be close-fitting to trap heat effectively, but not so tight they feel uncomfortable.
Men's thermals are specially designed base layers worn close to the skin. They gently trap body heat to keep you warm while allowing your skin to breather, so you stay comfortable throughout the day.
Thermals work best when they fit close to the body, as this helps to retain warmth. They shouldn't feel restrictive - just snug enough to move with you comfortably under your everyday clothing.
For particularly chilly days, choose heavier-weight thermals or pair thermal vest with long-sleeve tops and thermal bottoms.
Our thermals are easy to care for and machine washable. Washing at a gentle temperature and avoiding high heat when drying helps them last longer and keep their shape.
