Satisfy Running teams up with District Vision on a special edition version of their Keiichi sunglass. The transparent nylon frame features a tortoise leaf motif that is hand-applied and sand-blasted in Fukui, Japan. Each frame is injected with titanium for strength and a hypoallerenic, adjustable nosepad is mounted with titanium screws to help keep things light. Add it all together and you have a frame that weighs just 22 grams. It will also feature a limited edition DVSR002 lens with a silver mirror that is ideal for brighter conditions.
