The Sara W by Kaikkialla is an ultra-light, sustainably produced half-zip fleece long-sleeve shirt made from recycled material. Whether as a warm base layer or a thinner mid-layer, the shirt 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. Ideal for your trekking or mountain tours.
