The 120 Cool Tec Fast Upward Top W by Ortovox has been specially developed for all female mountaineers who don't want to do without natural climate management. The combination of the finest merino wool from Tasmania with Tencel, a fiber obtained from eucalyptus wood, makes the shirt even more robust while maintaining the same cooling effect. The Tencel fiber is round in cross-section with a smooth surface. Combined with the fine, soft merino fibers, the result is an incredibly comfortable, soft fabric that drapes beautifully. The Corespun technology ensures durability: both fibers are woven around a polyamide core, which makes the fabric more resistant and robust. It is fast-drying, regulates body temperature and has optimum moisture management. The close-fitting cut ensures plenty of freedom of movement and a comfortable fit. An ideal lightweight for various alpine activities on hot summer days.
