Product information

An insulated jacket for freezing and exposed conditions, the Eigerjoch Pro Insulated jacket uses a double-chamber construction to adapt different zones of the jacket to specific requirements of the body. PrimaLoft is used for areas exposed to moisture as well as for the inside of the jacket, while the remaining zones feature warm down filling for maxium warmth-weight performance. The insulated jacket comes with an additional stow bag with two carabiner loops.
