The purpose of the La Sportiva Odyssey GTX mens jacket is to give a level of protection against wind and water, while keeping the weight and constructions of the jacket at a very reduced level. It only weighs 212g, so it\'s naturally super convenient to pack away on trips out, events etc.. To achieve the light weight but max. protection, the Odyssey used the lightest Gore-Tex Active shell fabric available on the market.
