The Flying Fisherman Solstice 7311 Polarized Sunglasses combine the best performance and style with features built for fishing. These medium-fit frames are vented to allow airflow to reach the back of the lenses and create an antifogging effect. They are also made from Grilamid TR-90, which is a durable polymer that is extremely lightweight, impact-resistant and heat-resistant. It has comfort features like recessed nose pads and co-injected temple pads to ensure a stay-put fit when the action strikes.
