The Sara M by Kaikkialla is an ultra-lightweight half-zip fleece long sleeve shirt made from recycled material. It is ideal for wearing on trekking or mountain tours - as a warm base layer or as a thinner mid-layer. The material feels soft against the skin, keeps you warm and offers you full freedom of movement in the upper body thanks to the elastane content. It has flat seams, elasticated cuffs and an extended back for even higher comfort. If you get too warm, you can use the zipped collar to provide more ventilation at any time.
