Oscar -20° is the warmest winter bag in the technical Oscar family, making it the natural choice for more extreme adventures. The tubic construction, where the chambers are running lengthwise, distributes the air quality throughout the bag creating an even insulation in all sections offering the best warmth to weight ratio yet seen. The shark-fin foot box offers easy ventilation allowing the feet to cool down. To protect against cold a wind membrane has been added. Together with the 3D winter hood, this makes Oscar a great choice for sleeping in the open, in a hammock or in a shelter.
