CARE INSTRUCTIONSShowing your blanket some TLC is the best way to ensure you'll reap its full benefits over the long haul. But accidents happen and when it does we recommend following these instructions:

1. Spot Cleaning
We always recommend spot cleaning as it is the safest method.

2. Hand Wash
Hand washing your blanket is your next best alternative to extend the life of your blanket. Please use cold water and a minimal amount of pH-neutral silk detergent.

3. Machine Wash
Machine washing should only be your last resort. Use silk detergent and set your washing cycle to the gentlest setting (usually labeled as ''delicate'') with cold water no more than 30°C/ 86°F.

4. Air Drying
We strongly advise against wringing your blanket. Instead, we recommend air drying it away from direct sunlight.

LEAKING OF SILK STRANDSWe've selected a silk filling and a TENCEL™ shell to ensure the softness and thermoregulation of this product. These materials are extremely smooth by nature, with an incredibly low rate of friction. This means more love and care for your skin, but also a higher chance of silk strands leaking out of the shell. This is normal and should not interfere with usage.

We suggest you:
Use scissors to gently cut off the silk strands without pulling them out any further.
Gently pat the area to restore the fluffiness and even out the distribution of the filling.

Please contact us if you see an abnormal amount of leakage, we have you covered by a 30-day free return and 1-year warranty that will get you sleeping in Heartcosy peace in no time!

It is so soft and keeps us cool, I highly recommend for hot sleepers!

Beacher Reynolds
Soft as it looks

Tag says 80% silk and 20% cotton core. I don’t know what that means because it feels like 1 layer. Very soft like a gigantic babies blanket.
