Advanced Thermal Solutions for Maximum Workplace Comfort

The ideal base layer should behave like a second skin, trapping body heat while efficiently drawing sweat away from the skin. Our expertly curated selection includes several specialised garment profiles to suit different active roles and weather conditions:

  • Long Sleeve Performance Base Layers: Excellent for active field technicians, construction crews, and athletes, styles like the Rhino Baselayer Long Sleeve offer streamlined muscle support and superb moisture management to keep workers dry and comfortable.
  • Thermal Long Johns & Leggings: Essential under-layer protection for outdoor staff working through freezing British winters. Options such as Regatta Thermal long johns or Spiro Bodyfit leggings ensure full-body insulation without adding bulky weight beneath work trousers.
  • Specialist Mid-Layers & Fleece Pullovers: Designed to bridge the gap between undergarments and heavy outerwear, garments like the Stormtech Pulse Fleece Pullover offer exceptional temperature control and adaptability for fast-changing environments.
  • Industry-Specific Underscrubs: Specifically tailored for medical, beauty, and care professionals, styles like the Onna by Premier 'Unstoppable' fresh underscrub base layer offer breathable, hygienic comfort beneath daily work garments.

Market-Leading Trade & Performance Brands

To ensure your corporate apparel withstands intensive wear, maintains stretch memory, and survives rigorous commercial laundering, we only partner with industry-approved apparel brands. Explore advanced thermal tech from heavy-duty workwear specialists like Snickers and outdoor experts Regatta, high-performance athletic cuts from Rhino and TriDri, and premium climate-control garments from Stormtech.
