The Fjällräven Abisko Wool SS M is a minimalist t-shirt in a soft jersey knit made from merino wool and polyester. This gives you the best of both worlds - the temperature-regulating properties of merino wool and the durability and fast-drying properties of synthetic fiber. The short-sleeved shirt is the perfect base layer in all temperatures and climates - whether cold or warm. The Abisko Wool SS likes to go hiking with you for a long time, as its wool naturally prevents the formation of unpleasant odors.
