The Abisko Wool Classic SS M by Fjällräven is simply classy. It is made from a pleasantly soft jersey knit material that is half merino wool and half polyester. This way, you get the best of both worlds – the temperature-regulating properties of merino wool as well as the durability and moisture-wicking qualities of synthetic fibers. A large graphic is placed on the front. The short-sleeve shirt is the perfect base layer for all temperatures and climates – whether it's cold or warm. The Abisko Wool Classic SS is eager to accompany you on long hikes, as its wool naturally prevents the formation of unpleasant odors.
