Helly Hansen W LIFA MERINO KNITEVO 1/2 ZIP Jacket

Designed for women who enjoy winter sports, the Helly Hansen W LIFA MERINO KNITEVO 1/2 ZIP Jacket is intended as a technical layer for mountain outings and winter activities. This half-zip thermal base layer combines a merino wool outer layer with an inner layer of LIFA® fibers to effectively manage heat and moisture. This gives you a versatile top for ski touring, resort skiing, or mountaineering, featuring a non-irritating fabric and flatlock seams designed for comfort.

Women’s Thermal Base Layer for Winter Activities

Designed for women and part of the WINTER collection, the Helly Hansen W LIFA MERINO KNITEVO 1/2 ZIP Jacket falls into the category of winter fleeces and softshell jackets as a technical base layer. Its two-layer construction combines a 100% merino wool outer layer with a LIFA® fiber inner layer, providing a balance of thermal insulation and moisture management for ski touring, camping, mountaineering, or resort skiing. With its long sleeves and half-zip collar, it moves with you and adapts to varying levels of exertion in the mountains, while remaining comfortable for everyday wear thanks to its non-irritating fabric and flatlock seams.

LIFA® MERINO Technology and Non-Irritating Comfort

The LIFA® MERINO technology in this thermal base layer features a two-layer construction: the merino wool outer layer regulates body heat, while the polypropylene inner layer, infused with LIFA® fibers, optimizes moisture wicking. This combination of materials—57% merino wool for the outer layer and 43% polypropylene for the inner layer—is designed to provide a fabric that doesn’t irritate the skin, even during prolonged wear. Flatlock seams enhance this comfort by minimizing friction, which is especially appreciated during back-to-back days of ski touring or mountaineering ascents in cold conditions.

Practical half-zip and care instructions suited for merino wool

The half-zip on the front allows for easy adjustment of the collar opening to regulate ventilation based on activity intensity or weather conditions while maintaining good coverage of the upper body. Weighing 305 g, the Helly Hansen W LIFA MERINO KNITEVO 1/2 ZIP Jacket is designed as a midweight thermal base layer, ideal for winter activities where heat and moisture management are essential. Care instructions respect the nature of merino wool: it is recommended to use a detergent specifically designed for wool, avoid adding fabric softener, wash the garment inside out without wringing it out, and close the zippers before washing. These precautions help preserve the performance of the LIFA® fibers and merino wool season after season.

The Helly Hansen W LIFA MERINO KNITEVO 1/2 ZIP Jacket thus offers a blend of merino wool and LIFA® fibers designed for women who engage in demanding winter activities, serving as a technical base layer.
