The Huk Waypoint Running Lakes Shirt is a must-have for your days on the water. Made from recycled plastic bottles, we have created our softest and lightest fabric yet, while keeping plastic out of the waterways. The bottles are cleaned, crushed, melted and stretched into fibers that are woven into yarns. This then becomes a durable fabric that features 50+ UPF rating to keep you protected from the sun. The Waypoint Collection: Protect the Water. Protect your Skin.
