Silk all the way! I have a purple one I got on Amazon and it feels so nice on my skin plus it doesn’t leave any sleep wrinkle lines on my face from using it all night.

Here’s the link for the inexpensive one I have:

Silk Sleep Mask & Blindfold, Soft Eye Mask with Adjustable Head Strap, Deep Rest Eye Masks for Sleeping Night Eyeshade, Eye Cover for Travel, Shift Work & Meditation (Purple) https://www.amazon.com/dp/B072JYJFD5/ref=cm_sw_r_cp_api_i_uGrWDbYS5QH33
