When casual days call for something more stylish but still require gear for staying warm in the outdoors, get a Smartwool Men's Sparwood Half Zip Sweater. Lightweight and designed for movement, it has a rib-knit collar, hem, and cuffs for added comfort and a regular fit for a sleek, modern look. While you get the confidence that you are looking quite dapper, you also benefit from the material itself. The blend of recycled polyester, Merino wool, and nylon provides flexibility, warmth, and breathability.
