M Silkweight LS Shirt

Color: Poseidon
Size: M
Whether you need an ultralight, breathable base layer or quick-drying sun protection, the NRS Men's Silkweight Long-Sleeve Shirt is purpose-built for warm-weather comfort and on-the-water performance.
  • 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.
  • Integrated antimicrobial elements in the fabric prevent the build-up of funky smells.
  • Our seam placement avoids high-friction zones, enhancing athletic performance and letting you row, paddle and swim in comfort.
  • Laser-cut thumbholes extend sun protection to the tops of your hands without adding unnecessary bulk to the cuffs.
  • Regular fit for casual comfort by itself, under a PFD or as a base layer for technical outerwear.
  • Slightly dropped rear hem provides additional coverage.
