Helly Hansen Lifa Merino Thermal Trousers 75506

When the temperature drops and you're facing demanding work in cold conditions, these thermal trousers deliver the performance you need. The Helly Hansen Lifa Merino combines merino wool with advanced Lifa® technology to create a powerhouse base layer that handles both warmth and moisture management. The merino wool keeps you insulated on the coldest days, whilst the Lifa® system actively wicks sweat away from your skin, keeping you dry and comfortable during intense activity. Flat seams run throughout for a smooth, irritation-free fit, and an elasticated waist provides flexibility without compromising security. These active long underwear trousers come with a gusseted crotch insert for enhanced durability and freedom of movement. Ideal for outdoor work, winter layering, or any role that demands serious cold-weather protection.

Key Features

• LifaStay Warm technology regulates body temperature effectively

• Elasticated waist with gusseted crotch for comfort and mobility

Recommendations from our Unishore Expert

These thermal trousers excel when you need reliable insulation without bulk. The combination of merino wool and polypropylene creates a balanced performance that keeps you warm whilst managing perspiration, so you stay dry throughout your shift. The gusseted crotch is a practical addition that prevents tearing during demanding movements, and the flat seams mean no irritation even during long working days. Layer these under your regular work trousers for enhanced warmth, or pair them with the matching Lifa Merino Crewneck or Half Zip top for a complete thermal system. They're particularly effective for outdoor roles, winter maintenance work, or any environment where cold exposure is a regular challenge.
