About This
- OUR DUVET COVER IS BACKED BY THE GOOD HOUSEKEEPING SEAL: Experience the difference in comfort and quality with our award-winning luxurious 400 thread count sateen 100 percent cotton duvet cover twin / twin XL. Feel the natural softness and breathable feel of the fabric against your skin. Independently tested to earn the prestigious Good Housekeeping Seal. Our product also won the GH Best Bedding award in 2025.
- IMPORTANT NOTE ON THIS COLOR: This a serene pale blue with soft gray undertones—a whisper-soft hue that adds a calm, airy touch to your bedroom. Please note, this not a bright or baby blue, but a gentle, muted pale blue. Made from the same 400 thread count fabric as our sheet sets and pillowcases for a coordinated look (each sold separately).
- 1 TWIN XL / TWIN SIZE DUVET COVER ONLY (COMFORTER NOT INCLUDED): 1 sky blue duvet cover twin / twin XL only (68" wide x 92" long) features high-quality stitching along with button openings and 4 internal ties for enduring durability and convenience. Please measure your comforter size to evaluate if our twin XL/ twin size duvet covers are a match.
- DURABLE, COLORFAST & EASY CARE: Protect your duvet insert or comforter without the hassle of washing the entire comforter. Our twin XL / twin size 100% natural cotton sateen duvet cover is easy to wash and dry at home at regular settings. The smooth sheen of the cotton sateen fabric gives your bed a crisp, elevated look. Every item bearing the OEKO-TEX STANDARD 100 label is certified as having passed safety tests for harmful substances.
- OUR COMMITMENT: We prioritize comfort, community, and sustainability. Since 2022, we've donated over 36,000 bedding items to US charities and removed plastic from our packaging. Sheets are crafted in our family‑owned factory in India with care and quality‑checked—thread count may vary by ±5% due to standard manufacturing limits. Thoughtfully crafted for everyday comfort.

Tired of Waking Up Hot and Uncomfortable?
Most people don’t realize that poor-quality bedding traps heat and blocks airflow, leading to restless nights and constant discomfort.
Synthetic fabrics, low breathability, and heavy materials can make your bed feel warm, sticky, and irritating — especially during warmer nights.
If you’re constantly searching for “cooling bedding” or “best sheets for hot sleepers,” you’re not alone.
