Keeps the cold out: the Rime IN Hybrid Flex Jacket Women insulating jacket is made of lightweight, elastic and water-repellent Pertex® Quantum Air material for increased breathability and freedom of movement. While you are applying yourself to a strenuous ascent, moisture can be wicked away to the outside, but water cannot penetrate from the outside. The insulating jacket is filled with stretch insulation for optimal heat retention and increased freedom of movement, which is also optimized through the elastic lining material. Stay warm despite the cold temperatures in this insulating jacket.
