Extra warm merino underwear for the best heat retention even in bitter cold. The Tech Thermo Merino Longsleeve from Icebreaker is superior to any synthetic functional underwear in terms of thermal performance and low heat loss when wet. This thermo merino functional underwear extracts much less fluid from the body and prevents colds through even temperature compensation. The merino long-sleeved shirt is therefore not only the ideal merino ski underwear in icy temperatures, but also for all outdoor activities in winter or expeditions. The naturally antibacterial effect of the wool fibers makes it possible to wear the merino longsleeve on multi-day tours without changing underwear. This saves a lot of weight, especially in winter. The wool for this merino functional underwear comes from the New Zealand Alps, where the climatic conditions produce the finest wool quality.
