Helly Hansen Lifa Merino Half Zip Thermal Shirt

When you're gearing up for demanding work in cold conditions, you need an active long sleeve undershirt that genuinely performs. The Helly Hansen Lifa Merino Half Zip 75107 combines two technical fabrics to deliver what matters most: effective moisture management paired with genuine warmth retention. The blend of merino wool and polypropylene works together to pull sweat away from your skin whilst keeping you insulated when temperatures drop.

The engineered seam construction, including shoulder and side seams eliminated entirely with flat seams throughout, removes pressure points during extended wear. Pair it with matching Lifa Merino bottoms for a complete layering system that handles whatever your work throws at you.

Key Features

• 57% merino wool and 43% polypropylene blend for superior performance
