Helly Hansen Men's Baselayers

Frequently Asked Questions

• What makes the Helly Hansen LIFA Merino Midweight base layers different from other baselayers?

  The LIFA Merino Midweight pairs an inner LIFA® moisture-transport layer with a soft merino-wool outer, creating a two-layer system that pulls sweat away from skin and traps insulating air for cold conditions. That dual construction delivers higher warmth and better odor control than basic single-layer thermals while keeping stretch for active mountain use.
• How should the LIFA Merino Midweight fit and which size should I choose?

  These pieces are intended to be snug and close-fitting—tight enough to move moisture away from skin but stretchy enough to avoid restriction during climbing or skiing. Use Helly Hansen’s size chart and your body measurements as your primary guide; if you plan bulky midlayers over them, consider sizing up one increment for extra room.
• What activities and conditions are the LIFA Merino Midweight baselayers best suited for?

  They’re designed for cold-weather mountain sports that combine sustained exertion and movement—think alpine skiing, ski touring, and technical climbing—where warmth, moisture management, and stretch are critical. Because they’re Helly Hansen’s warmest midweight option, they perform best in cold conditions or as a warm base under insulated layers.
• How does the LIFA Merino Midweight compare to a standard synthetic midweight baselayer?

  Compared with single-layer synthetic midweights, the LIFA Merino Midweight’s two-layer construction offers a warmer, softer outer next to the skin (merino) while the LIFA® inner actively transports moisture to the exterior. Synthetics can dry very quickly and can be lighter, but LIFA Merino balances insulation, odor control, and next-to-skin comfort for sustained cold-weather activity.
• How should I care for LIFA Merino Midweight baselayers to preserve performance?

  Wash on a gentle cycle with cold water and a detergent formulated for wool blends, avoid fabric softeners and bleach, and reshape before drying; air-drying is best to protect the merino fibers and LIFA® layer. Avoid high-heat tumble drying or ironing to maintain stretch, loft, and moisture-wicking performance.
