The Rays Stretch Vent Shirt Men by Jack Wolfskin is a short-sleeve outdoor blouse designed for active use in warm conditions. It’s intended to wick moisture away, offer sun protection and allow freedom of movement, making it a go-to layer when you’re hiking, traveling or spending time outdoors.
Made from a blend of 95% polyamide and 5% elastane, this shirt has a bit of stretch that follows your movements, reducing any restriction during climbs or reaches. The quick-drying fabric helps you stay comfortable on humid days or when you pick up the pace, while the regular fit sits close enough for layering without feeling tight. Its UV construction provides extra protection from the sun, and the Bluesign® certification shows the materials meet strict environmental and safety standards.
Nylon Stretch UV refers to a fabric treatment and construction that combines durable nylon fibers with elastane for flexibility, plus built-in ultraviolet protection—so you don’t need a separate sun shirt. The Bluesign® label indicates the textile has been vetted for low environmental impact across its production stages, ensuring responsible use of resources and minimal harmful chemicals.
