This ultra light 80 gram packable jacket has an OSM Shield, which among other things means that it is water-repellent. The jacket can be folded into one pocket so that it does not take up more space than it can be in the bag, glove compartment or bicycle basket. The jacket is made with an OSM shield that adds the extra value by keeping you dry and comfortable. Furthermore, it has a continuous zipper and 2 pockets. Fabrics treated with OSM Shield also require fewer washes, significantly less drying time and less detergent.
