Light as a cloud, warm exactly where you need it.
A soft, lightweight comforter set with a washed semi-nanofiber shell and antibacterial corn-derived fill. The yarn is less than 1/100 the thickness of a human hair and woven tightly, so the fabric stays clean-feeling and sheds almost no lint. The corn fill is rated at 99.9% antibacterial performance and holds more warmth than standard fiberfill while staying light. Made in South Korea from fabric to final inspection.
Key Features
- Semi-nanofiber washed fabric — Yarn under 1/100 the thickness of a human hair, densely woven so dust and lint stay out.
- High-temperature washed finish — The fabric is washed at high heat to strip impurities, leaving a soft, peach-like surface.
- 99.9% antibacterial corn fill — Plant-derived corn fiber fill with verified antibacterial performance, an animal-free alternative to down.
- Holds warmth, recovers loft — Warmer than standard fiberfill and springs back after washing or compression.
- Straight-line jump quilting — Minimizes fill clumping while letting the comforter drape close to the body.
- Point line detail — A finishing line runs along three edges of the comforter for a cleaner look.
- Same pattern on both sides — Both faces are finished identically, so there is no wrong side up when you make the bed.
- Verified for harmful substances — The fabric has passed hazardous substance testing.
- Bed pad with non-slip backing — Elastic corner banding and a non-slip back keep the pad in place.
- Made in South Korea — Fabric, cutting, sewing, inspection, and packing all done in South Korea.

Care Instructions
Care Instructions
- Place bedding in a large laundry bag before washing.
- Use a large-capacity washing machine, preferably 44 lb (20 kg) or larger.
- Machine wash separately in cold water at or below 86°F (30°C).
- Use a gentle or wool cycle.
- Use a neutral detergent without bleach.
- Allow the bedding to become fully saturated with water before washing.
- Use a gentle spin cycle.
- Do not tumble dry.
- Air dry naturally in the shade.
- Gently shake out the bedding after washing before use.
- Wash dark colors separately before first use, as they carry a higher risk of color transfer. The darker the color, the more we recommend washing it separately two or more times.
- Avoid prolonged direct contact with light-colored items, furniture, wallpaper, and other fabrics.
Note: The set ships compressed and regains its full loft naturally once opened. All-season comforters may be produced at slightly different thicknesses depending on the season; this is not a defect. Sizes may vary by approximately ±2.0" (±5 cm), which is normal for fabric products. King-size pieces have a seam where the fabric panels join. Pigment-washed items are dyed after the care label is attached, so the label is dyed the same color; this is not a defect. Faint pin marks from fabric handling may remain. Dye lots vary slightly between production runs, so the same color may look a little different. Damage caused by color transfer is not covered.

Clean, hygienic, and I'm happy with it. Recommend.
I liked another comforter I bought from here before, so I bought a set for our newlywed home. It feels great and I love it. Love the deep green color too. I'll shop here again.
Using it and it's cozy for between seasons. The color isn't dull, and even after washing and drying, the filling doesn't go flat. It stays fluffy. Very cozy.
So pretty and the color is nice. The fabric is soft too, which I loved. Great comforter. The thickness is perfect for this season. I have allergies and it seems good for that.
Fluffy and nice. Bought the comforter first to start decorating.
