What are the care instructions for the Duvet Cover Set?

What is the difference between a duvet insert and a duvet cover?

A duvet insert is the fluffy, quilted blanket that keeps you warm (like our Helix Down Alternative Duvet Insert). A duvet cover goes over the insert to protect it and make it easy to wash. Together, they create a complete, customizable sleep system. You can swap out covers to match your style or season without replacing the whole duvet.

Why blend cotton and bamboo?

We wanted to combine the benefits of cotton, which is durable and soft, and bamboo-derived rayon, which is naturally moisture-wicking and pulls more heat away from your body than cotton alone. It's also softer and more sustainable: bamboo grows quickly and requires less water than traditional cotton. The result? A cover that feels cool, smooth, and lasts longer.

How does this duvet cover compare to 100% cotton duvet covers?


100% cotton duvet covers are durable and breathable, but they can feel heavier and trap more heat. By blending cotton with bamboo-derived rayon, we created a cover that's softer, cooler, and more moisture-wicking, while still offering the durability of cotton. If you sleep hot or want year-round versatility, this blend is a great choice.

Does this fit standard duvet covers, or just the Helix Down Alternative Duvet Insert?


Our duvet cover is designed to fit standard duvet inserts, including our Helix Down Alternative Duvet Insert. It features corner ties and a hidden zipper to keep any insert securely in place. Available in Twin/Twin XL, Full/Queen, King/California King sizes.

What thread count should I look for in a duvet cover?


Thread count measures how tightly woven the fabric is. Higher thread counts (300+) feel smoother and more durable, but are thicker and can inhibit breathability. We chose 300 thread count because it perfectly balances softness, durability, and airflow, so you get a cover that feels smooth but doesn’t trap heat inside.

Is this cover noisy or crinkly?


No. Our cotton-bamboo blend is seriously soft and smooth from the first night, without any stiffness or crinkling. It only gets softer with every wash.
