With amazing stretch and a soft feel, it's incredibly comfortable and addictive. Easy care: you can easily wash it in your home washing machine and it dries in about 3 hours. It's also resistant to pilling and doesn't lose its shape, so the high-quality texture lasts.

Thank you for viewing. I think it's clean because I've only worn it once. Please refrain from purchasing if you are concerned about minor signs of wear. Thank you.
