Abstract: A sun protective headwear system is provided. The sun protective headwear system may include a headwear having a body and brim portion with a novel sun protective inner lining. The inner lining may incorporate recycled water bottles to achieve advantageous sun protective properties. A closure mechanism may be provided along a rear body portion, near a tensive brim seam joining the brim portion to the body portion, so that in a closed condition the closure mechanism maintains the shape of the headwear while adjusting its fitting so as to be suitable across a wide range of head sizes. The sun protective headwear system may also include a packable pouch dimensioned and adapted to be crushably folded when the packable pouch houses the headwear.
