The Fjallraven Bergtagen Midlayer Hoodie is a pullover hoodie in a recycled polyester and wool blend, with a grid-textured inside face that holds warm air close to the body. The fabric wicks moisture, dries quickly, and helps regulate temperature on hard climbs and cold stops. What Our Gearhead(R) Experts Are Saying:"On mild days I wear this hoodie by itself against my skin, and on cold ones I slip a thin baselayer under it and a shell over it. One hoodie covers both jobs."
