Women's - Collagen Sleepshirts - Solid w/ Piping - Beauty Fiber™

Sometimes comfort should be as simple as slipping into one effortless piece. Our Collagen Sleepshirt is made for easy nights, slow mornings, and travel, one beautifully comfortable piece that packs simply and makes winding down effortless wherever you are. And because the best sleepshirt should be about more than the way it looks, we made the difference something you can feel.

Beauty Fiber™ infuses marine collagen amino acids directly into the yarn, not simply applied to the surface—creating an exceptionally smooth, lightweight, breathable fabric that feels beautifully gentle against the skin. Finished with contrast piping, custom Kashwére buttons, and a breast pocket. Available in Morning Fog with White piping and White with Onyx piping. Fits true to size; size up for a more relaxed, oversized fit.

Sleep. Lounge. Recover.
