Product Information

An ultralight sun shirt that blends casual style with technical performance, the NRS Women's Silkweight Kosi Shirt features a quarter-zip neck for quick ventilation and thumbholes to extend its UPF 50+ sun protection.

• Built from 100% recycled material, the technical fabric enhances the body's natural cooling process by wicking excess moisture and drying quickly while also providing UPF 50+ sun protection.
• Our seam placement avoids high-friction zones, enhancing athletic performance and letting you row, paddle and swim in comfort.
• Regular fit for casual comfort by itself, under a PFD or as a base layer for technical outerwear.
• Quarter-zip neck provides quick ventilation, added comfort and a little style.
• Integrated antimicrobial elements in the fabric prevent the build-up of funky smells.
• Laser-cut thumbholes extend sun protection to the tops of your hands without adding unnecessary bulk to the cuffs.
• Dropped rear hem provides additional coverage when sitting.
