Whether we need a warm mid-layer for cold days on the mountain or a stand-alone jacket for a brisk fall hike, the Fjallraven Keb Fleece Hooded Jacket has us covered. The fabric construction features a mixture of polyester, wool, and elastane for a blend of warmth and mobility, while the addition of G-1000 reinforcements on the shoulders, made with recycled and organic materials, delivers long-lasting durability.
