• Construction workers on exposed building sites and outdoor projects
• Groundworkers and landscapers working in all weather conditions
• Agricultural workers and farmers during winter months
• Engineers and maintenance staff in unheated warehouses and industrial facilities
• Roofers and scaffolders exposed to wind chill at height
• Utility workers carrying out outdoor repairs and inspections

Choosing The Right Thermal Underwear

When selecting thermal baselayers from MyToolShed.co.uk, consider these important factors:

• Material composition: Synthetic fabrics offer excellent moisture-wicking properties and quick drying, whilst merino wool provides natural temperature regulation and odour resistance
• Weight and warmth level: Lightweight options suit moderate conditions and high-activity work, whilst heavier thermal layers provide maximum insulation for extreme cold
• Fit and mobility: Close-fitting baselayers trap warmth effectively without bunching under work clothing; ensure adequate stretch for unrestricted movement
• Sleeve length: Long sleeves offer full coverage, whilst short sleeve thermal tops work well as mid-layers or in milder conditions
• Specialist features: Antibacterial treatments reduce odours during extended wear, flame-resistant options meet safety requirements for specific industries, and high-visibility variants add safety benefits
• Washing requirements: Check care instructions to maintain thermal properties and garment longevity

Frequently Asked Questions

Can thermal baselayers be worn under work clothing?

Yes, thermal underwear is specifically designed as a first layer worn directly against the skin beneath your regular work clothes. The slim fit ensures they don't create bulk or restrict movement whilst providing insulation.

How do I determine the correct size for thermal underwear?

Thermal baselayers should fit snugly but not restrictively. Refer to the manufacturer's sizing charts and measure your chest, waist, and inside leg. If between sizes, consider the level of physical activity – more active work may benefit from a slightly looser fit.

Do thermal baselayers need special washing care?

Most thermal underwear can be machine washed at 30-40°C, but always check the care label. Avoid fabric softeners as they can reduce moisture-wicking properties, and air dry when possible to maintain elasticity and thermal efficiency.
