The Superior Silk U-Neck Shirt is the ultimate long-sleeve base layer for women who refuse to choose between performance and luxury. Made from 100% premium natural silk, this shirt provides full-arm coverage with a "weightless" feel. Silk is nature’s most sophisticated insulator—it creates a breathable microclimate against your skin, keeping you warm in chilly cabins or winter streets, yet remains remarkably cool when the sun comes out. It is the perfect travel companion for those with sensitive skin or anyone looking for a sleek, non-bulky layer.

Care Instructions

• Ironing: Usually unnecessary, but if required, use a cool iron with a press cloth.

Professional Tips from X-Boundaries

1. The "Hidden" Thermal: This is our favorite solution for winter business trips. It provides significant warmth under a professional shirt without the bulk or "sporty" look of a typical synthetic thermal.

2. Sensitive Skin Sanctuary: If winter air makes your skin dry or itchy, silk is a lifesaver. It doesn't strip moisture from your skin like some synthetics can, helping you stay comfortable all day.

3. The Ultimate Flight Shirt: Wear this on long-haul flights to deal with the constant flip-flop between freezing cabin air and stuffy terminals. It’s the most breathable long-sleeve you’ll ever own.

4. Protect Your Investment: Silk is a natural fiber. To keep it in peak condition, always use a Laundry Net to protect the sleeves from getting tangled or snagged in the wash.
