The Cooper is the vest version of the Wayside , bringing the same heritage-inspired mix of high-pile sherpa fleece and corduroy into a lighter layering piece. The recycled sherpa fleece delivers plenty of warmth through the core, while corduroy at the chest pocket, hand pockets, and inside neck adds structure and a little old-school texture. Elastic binding keeps the fit clean, and the full-zip front makes it easy to layer over a shirt or under a shell when temperatures start to move around. Warm where you need it, without committing to full sleeves.
