Because the hotel duvet has seen things. Meet your travel essential, redefined. Crafted from our signature Washable Stretch Silk, our sleep sack is a portable cocoon of breathable, touchably luxe protection. Consider it the ultimate layer between you and whatever housekeeping missed. The charmeuse interior keeps the smooth side against your skin (as it should be), while the built-in pillowcase pocket accommodates everything from travel-sized comforts to a full king-sized pillow (not included with Sleep Sack).  Reinforced side gussets add structure and longevity, because this isn’t a one-trip wonder. And it all rolls effortlessly into a sleek branded travel bag. Compact, elevated, and perfectly made to pair with our popular Washable Silk Travel Pillow.  Five-star softness, no matter your stay’s star rating.
