The Astroman Short Sleeve Sun Shirt delivers lightweight performance and reliable protection for climbing, hiking, and long days under the sun.
Made from a bluesign® approved recycled nylon blend, it wicks moisture, dries fast, and provides UPF 30 sun protection for extended wear outdoors. A hidden snap front keeps the look clean and functional, while a drop-in chest pocket stashes small essentials. The inverted back yoke with box pleat enhances mobility, and a raised heat-transfer logo adds a subtle, modern finish to this versatile layer.
