Recommendations from our Unishore Expert

When working in severe cold conditions, having the right thermal underpants makes a genuine difference to your comfort and safety. These long underpants excel at regulating body temperature whilst managing moisture, so you stay warm and dry throughout extended shifts. The merino wool composition naturally resists odour and maintains its insulating capability even when damp. The elastic borders at the waist and ankles prevent heat loss and keep the garment in position during demanding physical work. We recommend wearing these thermal underpants as your primary base layer under heavier workwear to maximise protection in extremely cold environments.
