First Ascent is a line of world-class expedition and ski wear created by Eddie Bauer with some of the best mountain and ski guides in the world. The perfect summer-weight solution for glacier travel, snowfield crossings or surf vacations, this sun-blocking, quick-wicking piece is the guide's choice to prevent overexposure on sun-baked days. UPF 30 . Features, Cocona technology, which microscopically increases surface area and harnesses body heat to speed evaporation of perspiration during high-output activities. Said simply: moisture moves faster so you stay dryer. And Cocona never washes or wears out. It's embedded in the fabric. Imported. "Whether you're in the mountains or at the beach, you need protection from the sun. This piece is designed to shield the sun's rays while keeping you cool and dry." - Seth Waterfall
