The Fjallraven Men's Down Jacket No.16 is an insulated jacket for outdoor durability and visibility. Wear alone or under a shell, either way the down insulation will ensure heat is trapped within. The G-1000® side is ready for work-wear, providing the durability needed, and can also be waxed for further weather protection. The blue side is all about visibility, wear it out if you're feeling the puffy look, but it is also one of the most visible colors in all terrain. Many functions, just one jacket.
