Norrona's most versatile ski/snowboard midlayer.This warm fleece jacket is made for freeriding and works for mountaineering, trekking, and general outdoor. They use two materials, one warmer and textured, and the other thinner and stretchier, to provide optimal thermal performance and comfort and because it offers excellent quick-drying and moisture-wicking properties. This structured material/fabric design is a way to reduce fabric weight while increasing warmth and compressibility. Open-air channels surrounding each segment of the grid allow easy release of all excess body heat as it builds during activity.
