This is the original (and very hard to find) Fjellpulken sled. What sets it apart is the fiberglass "hull", which simply glides nearly effortlessly compared to plastic imitations (more rigid, too!). It has a spring-loaded wooden backrest and adjustable windscreen. There is lots of room to bundle your little one in blankets and hit the trails. This has been a favorite past-time for our family, but the kids just grow up too fast!
