Engineered with body-mapped construction for optimal warmth and breathability
Since 1877, technical outdoor brand, Helly Hansen has been trusted by professionals, drawing on their insights and experience to drive product development. With innovation at its core, the Norway-based brand has introduced a number of industry firsts throughout its nearly 150-year history. For example, Helly Hansen introduced the first technical base layers in the 1970s.
An evolution of Lifa Merino – the unique two-in-one base layer combining proprietary LIFA® fibres next to the skin with a Merino wool exterior – the new Lifa Merino KnitEvo (SRP £120) takes performance even further. Its body-mapped construction features an open-knit structure in high-heat zones for enhanced breathability and moisture management. Meanwhile, a tighter knit, loftier Merino wool layer adds warmth where it’s needed most. New for Winter 2026, the new Lifa Merino KnitEvo styles deliver elevated performance across a range of winter activities. These winter activities include skiing, ski touring, hiking and mountaineering.
LIFA® revolutionised the industry when it was first introduced in 1970. The fabric is based on a yarn technology that moves moisture away from the skin and transports it to the surface of the fabric. There, it evaporates, leaving you warm, dry and comfortable. Lifa Merino builds on this technology with LIFA® fibres next to skin and a Merino wool exterior. Furthermore, Lifa Merino KnitEvo pushes performance even further, incorporating innovative engineered knit technologies and a body-mapped construction.
Informed by R&D and developed with ski professionals, including top athletes from Team Telenor Alpine Norway and Alpine Canada Alpin, who depend on their high-performance gear in tough conditions and high speeds, the new Lifa Merino KnitEvo Crew addresses varying thermal and moisture management needs across body zones. An open-knit structure in the back and underarms provides optimal breathability. On the other hand, RWS-certified ZQ Merino wool on the shoulders and upper arms adds targeted warmth. Flatlock seams and raglan sleeves ensure a comfortable fit with unrestricted movement.
Martin Cizeron, Product Manager for Outdoor at Helly Hansen, comments, “Our Lifa Merino base layers have become a trusted choice for both professionals and consumers seeking the perfect combination of comfort, warmth and performance. With the Lifa Merino KnitEvo, we’re building on that expertise – delivering the same warmth and comfort that we’re known for, now with enhanced thermal-management performance. It’s our most advanced base layer yet, designed to keep you warm and comfortable whether you’re on the slopes or in the backcountry.”
Ahead of its release, the Lifa Merino KnitEvo Crew has already been named an ISPO Award Gold Winner, the highest honour in its category, given to the top-scoring product for exceptional innovation and performance.
ISPO Award Jury Statement: “LIFA® moisture transport, Merino warmth and body-mapped engineering make the KnitEvo Crew a true winter performance upgrade.”
The new Lifa Merino KnitEvo styles – including the crew, a half-zip top, a three-quarter pant and midlayer jacket – will be available in both men’s and women’s specific designs in-store and online starting Autumn 2026.
