Thank you for your feedback. We’re sorry to hear that the satin pillowcase didn’t provide the cooling effect you were hoping for, especially in the summer. Satin fabrics can sometimes trap heat, and we understand that this may not be the best option for everyone.If you’re looking for a more cooling pillowcase, we offer other options designed with temperature regulation in mind. Please feel free to reach out to us at hi@discovernight.com if you'd like assistance with a return or exchange.
