Our LIFA® Merino Midweight collection is perfect for any type of activity in cold weather. We combined a Merino wool layer with our proven LIFA® Stay Warm tech in a 2-layer construction. LIFA® Merino Midweight delivers all the breathable warmth of merino wool fibers, plus the unique moisture management properties of LIFA® fibers. Basics don’t need to be boring; we upgraded the top with cool graphics.
