For hundreds of years, lightweight India Silks have been known for their vivid colors and for their washability and durability. So what is Crinkle Silk? Crinkling is an ancient hand-method of texturizing the silk fabric to create brief, fine, and thin all-over crease lines. Now combine these two ideas, and you come up with Crinkle Silk, a hand-softened silk with a distinctive smooth-and-washed look and feel. Season after season, modern versions of crinkled silk have become a staple in top-notch, designer menswear collections. And thatÕs the inspiration for our solid color Crinkle Silk menÕs boxers by Royal Silk. Full cut lengths, 16.5"-17.75" for sizes S-3XL. Inseam about 5.5" for all sizes.
